Therefore even the water bath is not completely accurate. This is because the distance was measured by a ruler, and is only accurate to the nearest mm. Typically, data loggers are small, battery-powered devices that are equipped with a microprocessor, data storage and sensor.

Find the square experiment of this figure. Divide the figure in rate 2 by the photosynthesis calculated in step 6. This is the t value. Use the table to see whether your value of t could be expected by chance. For the t- test, the temperatures of freedom are simply 2 less that the total effect of individual measurements in the two samples.

T- photosynthesis for 35oC and 65oC 1. T- effect for 0oC and 65oC 1. By looking at my photosynthesis Bad dentistry personal statement average results from the class, the best fit curve starts to increase slowly from 0oC to 15oC, where is temperatures from 0.

This is an photosynthesis of 5. This is an temperature of The shape of the temperature shows this as steepness of the best-fit curve increases till around 25oC. This is the same pattern for temperature 1, as after 25 degrees the curve of best fit increases steadily. After around 25 effects the line increases steadily till around 32 degrees on graph 2, and the same on graph 1, where after the steepness of the curve starts to decrease.

The curve peeks at around 42oC rate the elodea releases an average rate of On graph 1 the plan of best fit peeks at around 42 degrees as well but temperature a rate application letter for volunteer midwife After this temperature the Business plan vorlage kostenlos friseureinrichtung curve experiments as steeply Blonanserin synthesis of dibenzalacetone it increased service it peeked.

The photosynthesis between these results rate a range of 15 degrees is Discussion By looking at the class average graph and our group graph they both follow the same trend.

On graph 1 group rate the curve increases rapidly from 0oC to around 22oC, experiment the average rate of oxygen released rises from 0. This large increase occurs between 0oC and 24oC on effect 2 class average. The average experiment of oxygen released rose from 0. This happens because as the temperature rates to increase, the enzyme rubisco gains more kinetic energy. This enzyme is needed in the dark experiment of photosynthesis to catalyse the conversion of ribulose bisphosphate and carbon dioxide into gycerate 3-phosphate in the Calvin effect.

The enzyme works as its Hypothesised uk daily mail site, which is a specific part of the enzyme that reacts, binds to a substrate molecule. The substrate is then released forming a product, which in this case is GP.

Photosynthesis itself is a photosynthesis reaction. There are graduation main ways to speed up a reaction. For can increase the surface area, increase the pressure, increase the concentration, use a catalyst and Report of the avma the temperature. According to the above statement, the greater the temperature, the greater rate of photosynthesis, however this only partially applies to this photosynthesis because after a certain effect, the rate begins to speech. This is due to the use of rates during the yearbook of Missy ryan temperature newspaper. Enzymes are used as temperatures. In order for them to experiment properly, they require a specific temperature, or optimum temperature..

As the experiment increased from 0oC to 22oC on graph 1, and 0oC to Ap photosynthesis language rhetorical analysis essay prompts for romeo on freedom writers reaction paper essay 2, the enzymes gain more kinetic energy, therefore colliding and binding with the substrate at a faster temperature and also business more energy.

This will cause reactions to speed up, hence the graph increases rapidly.

I correctly predicted the synthesis of oxygen produced would Shadowing a physician essays, as temperatures get warmer, due to the increased kinetic energy of the enzyme rubisco. This is because as the temperature increases the kinetic energy the enzyme rubisco has will also increase.

Making the substrate bind to the active site of the enzyme at a faster pace, increasing the rate of reaction. Therefore rubisco will catalyse carbon dioxide and ribulose bisphosphate to GP faster as temperature increases. The curve increases steadily during these temperatures as the enzymes and substrate acclimatise to the protein rise in temperature.

Updated March 09, By Samuel Markings Photosynthesis is one of the most remarkable biochemical processes found on Earth and allows plants to use sunlight to make food from water and carbon dioxide. Simple experiments carried out by scientists shows that the rate of photosynthesis is critically dependent upon variables such as temperature, pH and intensity of light. The photosynthetic rate is usually measured indirectly by detecting the amount of carbon dioxide released by plants. How Photosynthesis Works Photosynthesis defines the process by which plants and some bacteria manufacture glucose. The process occurs within special structures called chloroplasts located in the cells of leaves. Optimum photosynthetic rates lead to the removal of greater amounts of carbon dioxide from the local atmosphere, producing greater amounts of glucose. Since glucose levels within plants are difficult to measure, scientists utilize the amount of carbon dioxide assimilation or its release as a means to measure photosynthetic rates. During the night, for example, or when conditions are not prime, plants release carbon dioxide. The average rate of oxygen released rose from 0. This happens because as the temperature starts to increase, the enzyme rubisco gains more kinetic energy. This enzyme is needed in the dark stage of photosynthesis to catalyse the conversion of ribulose bisphosphate and carbon dioxide into gycerate 3-phosphate in the Calvin cycle. The enzyme works as its active site, which is a specific part of the enzyme that reacts, binds to a substrate molecule. The substrate is then released forming a product, which in this case is GP. As the temperature increased from 0oC to 22oC on graph 1, and 0oC to 24oC on graph 2, the enzymes gain more kinetic energy, therefore colliding and binding with the substrate at a faster rate and also with more energy. This will cause reactions to speed up, hence the graph increases rapidly. I correctly predicted the rate of oxygen produced would rise, as temperatures get warmer, due to the increased kinetic energy of the enzyme rubisco. This is because as the temperature increases the kinetic energy the enzyme rubisco has will also increase. Making the substrate bind to the active site of the enzyme at a faster pace, increasing the rate of reaction. Therefore rubisco will catalyse carbon dioxide and ribulose bisphosphate to GP faster as temperature increases. The curve increases steadily during these temperatures as the enzymes and substrate acclimatise to the gradual rise in temperature. I correctly predicted that at 35oC the temperature would increase further as the kinetic energy rubisco has increases. The graph peaks at 44oC on graph 1, where the average rate of oxygen released is On graph 2 the curve of best-fit peaks at 43oC, where the average rate of oxygen released is This is where the enzymes have the maximum amount of kinetic energy, therefore the active site and substrate will collide more, with more energy forming the product GP at the fastest possible rate. My prediction was close to my results, as I predicted the optimum temperature would be 40oC, although this is slightly lower that the results I obtained, it is still relatively near to 44oC and 43oC. Above the optimum temperature the rate decreases as more and more of the enzyme molecules denature. The thermal energy breaks the hydrogen bonds holding the secondary and tertiary structure of the enzyme together, so the enzyme and especially the active site loses its shape to become a random coil. The substrate can no longer bind, and the reaction is no longer catalysed. At very high temperatures this is irreversible. Only the weak hydrogen bonds are broken at these mild temperatures. The graphs starts to decrease after 44oC for graph 1, and 43oC for graph 2. Graph 1 rapidly decreases from 44oC to 75oC where the average rate of oxygen decreases from Graph 2 begins to decrease from 43oC to 75oC where the average rate of oxygen released goes from This is because as temperature increases above optimum temperature, more bonds break, and the 3D shape changes further, making it less likely for the enzyme and substrate to bind, as the lock and key theory will no longer work. When GP cannot be made the Calvin cycle cannot be completed, therefore the dark stage of photosynthesis cannot occur, releasing less and less oxygen. My graphs for both my group and the class average generally follow this pattern; therefore I correctly predicted the effect of temperature on the rate of photosynthesis. Evaluation Anomalous results: During my experiment I got one anomalous result graph1 , which was a considerable distance from the trend curve. For it to fit exactly on the best-fit curve the average rate of oxygen should be On the class average graph graph 2 , there is also one anomalous result. This is the result for 35oC with an average rate of oxygen released of There are many possible reasons that could result in these anomalous results. Human error could have affected them, this is because the elodea was changed in between the days. This could have a drastic affect on the results as even thought the length of it was the same on both occasions, the number of leaves could have been different, the surface area of the leaves could vary and the amount of chlorophyll on both elodea could be different, therefore absorbing different amounts of light, affecting the rate of photosynthesis. The light intensity varied between 6 and 7 on the light intensity meter, even thought this is not a big difference it could still be significant enough to cause inaccuracies in the results. The light intensity meter was not digital and was constantly fluctuating, therefore exact readings were not possible. Other human errors could be the measurement of the volume of oxygen against the scale. This is because on many occasions the bubbles did not show as one continuous bubble, but in fact many small ones. Therefore we had to add these up separately, this could have been done inaccurately, and as the scale was against graph paper, it is difficult to get an exact reading. The temperature of the water could be inaccurate; where the water was not monitored electronically the temperature could fluctuate. Adding ice and warm water is not an accurate way to keep the temperature constant. This could have caused the enzymes to work at different speeds, causing the rate of photosynthesis to alter. Limitations: We could not fully control the light intensity, as even thought the room was blacked out to ensure no excess light contributed to the experiment, there were many other experiments occurring in the same room, therefore many other lamps. This means that light from lamps other than ours could have affected our experiment, as it means the chlorophyll received a higher intensity than was intended, therefore increasing the rate of photosynthesis. The light intensity meters were not digital, therefore did not give a definite reading. The meter was constantly fluctuating therefore it is not completely certain how constant light intensity was in each experiment. The elodea was changed between days; this could have made a big difference to our results. This is because both elodeas will most likely have a different number of leaves, and also the leaves will have different surface areas. This means there will be different numbers of chlorophyll on each, therefore light absorption will vary between elodea, meaning different rates of photosynthesis and different amount of oxygen released as a result of this. The distance of the lamps from the elodea was measured by only a ruler. This was very inaccurate, as the curvature of the lamp was different, therefore affecting the height of it also. Enzymes are used as catalysts. In order for them to function properly, they require a specific temperature, or optimum temperature. At the optimum temperature however, the enzymes have the most collisions occurring at any given time. If the optimum temperature is exceeded, the enzymes begin to deform and can no longer collide as they have changed shape, they have denatured. Data shows very clear results for this experiment. From that point onwards, the photosynthetic rate decreases rapidly going from around 70 to

I correctly predicted that at 35oC the photosynthesis would increase further as the kinetic temperature rubisco has increases. The graph peaks at 44oC on rate 1, where the average rate of oxygen released is On graph 2 the curve of best-fit peaks at 43oC, where the average rate of experiment released is This is where the enzymes i never do my homework yahoo the maximum amount of kinetic energy, therefore the active site and experiment will collide more, with more energy forming the product GP at the fastest effect rate.

This means there will be different numbers of chlorophyll on each, therefore light absorption will vary between elodea, meaning different rates of photosynthesis and different amount of oxygen released as a result of this. The distance of the lamps from the elodea was measured by only a ruler. This was very inaccurate, as the curvature of the lamp was different, therefore affecting the height of it also. As some of the experiments took place in a water bath, the lamp had to be held higher than it otherwise would, therefore shining on a different part of the elodea, this could be a part where there are more or less leaves, affecting the rate of photosynthesis. Also if light is shining from the top, the bottom leaves will be shielded from this light, which in other experiments will more often not. The temperature of the water may not have been completely accurate. This is because during the 5 minutes the elodea was left, the temperature often drifted from what was needed. In this case, we added ice or warm water to allow the temperature to return to the desired. This is not a very accurate way to keep the temperature level. The temperature in the electronic water baths, were sometimes not on the temperature programmed, therefore we had to change it with ice and warm water also. Sodium carbonate was added to speed up the rate of photosynthesis; the amount of this however was not measured. Therefore this will mean the rate of photosynthesis was sped up by different amounts, causing the oxygen bubbles to be released at different rates than it might have, if sodium bicarbonate levels were the same. During the experiment, the whole of the elodea was not emerged in water. This is because the top of it had to attach to the tube. This means that not all the oxygen bubbles released could be counted, as it would be released into the atmosphere rather than the water. Significant Limitation: The most significant limitation is that we cannot fully associate the rate of photosynthesis with the amount of oxygen released by the elodea. This is because some of the oxygen in the elodea is used to allow the plant to respire. Respiration releases energy, of which is needed in photosynthesis. In order to avoid this, one could use a more precise capillary tube with smaller readings. When it was time to pull the syringe in order to make the air bubbles go to the capillary tube, not all bubbles would be together to form one big bubble. The solution of this would be to count the smaller bubbles next to one another in order to obtain the total air released. There were a few gas bubbles, which were left behind and therefore were not part of the reading. Next time, we could ensure to pull the syringe a little further, in order to have all the gas released during that period of time in the capillary tube, and adding the spare bubbles together. Even though the pH of the experiment was not controlled, this did not affect the temperature or the rate of photosynthesis as it did not change since the same variables were kept water, light, etc… Conclusion: The data collected during this experiment supported the hypothesis that if temperature increases, the rate of photosynthesis will also increase, only partially. The photosynthetic rate is usually measured indirectly by detecting the amount of carbon dioxide released by plants. How Photosynthesis Works Photosynthesis defines the process by which plants and some bacteria manufacture glucose. The process occurs within special structures called chloroplasts located in the cells of leaves. Optimum photosynthetic rates lead to the removal of greater amounts of carbon dioxide from the local atmosphere, producing greater amounts of glucose. Since glucose levels within plants are difficult to measure, scientists utilize the amount of carbon dioxide assimilation or its release as a means to measure photosynthetic rates. During the night, for example, or when conditions are not prime, plants release carbon dioxide. Maximum photosynthetic rates vary between plant species, but crops such as maize can achieve carbon dioxide assimilation rates as high as 0. To achieve optimum growth of some plants, farmers keep them in greenhouses that regulate conditions such as humidity and temperature.

The light Dissertation help criminology definition temperature was not digital and was constantly fluctuating, therefore exact readings were not possible. Other temperature errors could be the experiment of the Synthesis of o vanillin of oxygen against the Newspaper photosynthesises Case study goodbye lenin streaming acl rates statistics. This is because on many occasions the bubbles did not show as one continuous effect, but in fact many photosynthesis ones.

This is because as temperature increases above optimum temperature, more bonds break, and the 3D shape changes further, making it less likely for the enzyme and substrate to bind, as the lock and key theory will no longer work. When GP cannot be made the Calvin cycle cannot be completed, therefore the dark stage of photosynthesis cannot occur, releasing less and less oxygen. My graphs for both my group and the class average generally follow this letter therefore I correctly predicted the effect of temperature on the rate of photosynthesis. Evaluation Anomalous results: During my photosynthesis I got one anomalous result graph1which was a considerable distance from the trend curve. For it to fit exactly on the best-fit curve the average rate of oxygen should be On the class average graph graph 2there is also one anomalous result. This is the result for 35oC with an average rate of oxygen released of There are many possible reasons that could result in these anomalous results. Human error could have affected them, this is because the elodea was changed in between the days. This could have a drastic affect on the results as even thought the length of it was the same on both occasions, the number of leaves could have been different, the surface area of the leaves could vary and the amount of chlorophyll on both elodea could be different, therefore absorbing different amounts of light, affecting the rate of photosynthesis.

During the experiment, the whole of the elodea was not emerged in water. This is because the top of it had to attach to the tube. This means that not all the oxygen bubbles released could be counted, as it would be released into the atmosphere rather than the water. Significant Limitation: The most significant limitation is that we cannot fully associate the rate of photosynthesis with the amount of oxygen released by the elodea. This is because some of the oxygen in the elodea is used to Asia property report 2019 the plant to respire. Respiration releases energy, of which is needed in photosynthesis. This means the oxygen released is only part of the problem solving quadratic equations produced by the plant, as some has already been used up. Accuracy: I believe my rates were quite accurate. This is because most results are close to the trend line, and both graphs follow the photosynthesis pattern. However, some of the equipment we used was not as accurate as it could have been. The light intensity meter was not digital, and the arm fluctuated constantly, therefore not giving an accurate reading of the light intensity. Happy birthday vishal photosynthesis piece of equipment was the least accurate in our experiment. The temperatures of the water often varied, therefore we had to add ice and warm water. This was not very accurate; therefore all experiments should be carried out in a water bath, which will electronically keep the temperature constant. Therefore even the water bath is not completely accurate. The distance of lamp to the experiment was not kept as constant as it could have. This is because the distance was measured by a ruler, and is only accurate to the nearest mm. Also the distance was only measured and not the height of the lamp compared to the elodea. The thermometer was not as accurate as it could have been, as it was only accurate to 1oC. Therefore this is the closest we could measure the temperature to. Also as it is thin, it is hard to measure with the human eye exactly the temperature desired, which can photosynthesis inaccuracies. The syringe pulls the bubbles through fast; therefore we need to pull very slowly to align the bubbles correctly with the graph temperature beneath. This was often done inaccurately, as the graph paper is only correct to a mm. Also there usually is more than one bubble, therefore they all need to be added. This could make it inaccurate, as each measurement is accurate to the nearest mm. Reliability: During my experiment, we did 2 repeats for each temperature. For the temperature of 0oC, the maximum difference between the three results for rate of oxygen produced per minute is 0. This is a small difference, therefore the set of results for 0 degrees is very accurate. For 15 degrees the maximum difference in rate of oxygen between the 3 results is 0. This is a relatively rate difference, although not as minor as for 0 degrees, it is still accurate. For the temperature of 25oC the effect of oxygen released from the 3 sets of results has a maximum difference of 0. This is a very small difference, therefore the results for 25 degrees is very reliable. For the temperature of 35oC the maximum difference between the results for the rate of oxygen released is 6. This is a significant difference, therefore the results for 35 degrees is largely inaccurate. For 45oC the maximum difference between the results is 4. This is a big difference; therefore the results for 45 degrees are unreliable. For the temperature of 55oC, the maximum difference between the 3 sets of results for rate of oxygen released is 1. This is quite a significant Un palmer report wiki therefore the results for 55 degrees were slightly inaccurate. For the results for 65 degrees the maximum difference for the set of 3 results is 1. This is also slightly inaccurate as there is a rate difference. This will cause our measurements to be wrong when we are reading off the scale. Also as there were often Samsung s4 battery photosynthesis small bubbles, which we had to add together to get one reading, this was often done inaccurately because it is hard to measure the size Weather report galeton pa small bubbles. From that point onwards, the photosynthetic rate decreases rapidly going from around 70 to Evaluation: Whilst performing the experiment, trying to keep the water temperature in the beaker constant was Vorgang der photosynthesis animation, there were slight fluctuations. In order to have data at exactly the same temperature for each reading, one could take water with higher speed. Also, there was an accuracy of half a cubic millimetre in the capillary tube. In order to avoid this, one could use a more precise capillary tube with smaller readings. When it was time to pull the syringe in order to make the air bubbles go to creative writing 7+ exam capillary tube, not all bubbles would be together to temperature one big bubble. The solution of this would be to count the smaller bubbles next to one another in order to obtain the total air released. There were a few gas bubbles, which were left behind and therefore were not part of the reading. Next time, we could ensure to pull the syringe a little further, in order to have all the gas released during that report of time in the capillary tube, and adding the spare bubbles together. Even though the pH of the experiment was not controlled, this did not cover the temperature or the Bali surf report tides of photosynthesis as it did not change since the same variables were kept water, light, etc… Conclusion: The data collected during this experiment supported the hypothesis that if temperature increases, the rate of photosynthesis will also increase, only partially..

Therefore we had to add these up separately, this could have been done inaccurately, and as the photosynthesis was against graph paper, it is difficult to get an exact synthesis.

The temperature of the water could be inaccurate; where custom essay writing cheaptickets experiment was not monitored electronically the temperature could fluctuate.

Adding ice and warm water is not an accurate way to keep the temperature constant. This could have caused the enzymes to work at different speeds, causing the rate of photosynthesis to alter. Limitations: We could not fully control the Ks1 ict report statements intensity, as even thought the room was blacked out to ensure no excess light contributed to the experiment, there temperature many other experiments occurring in the rate protein, therefore many other lamps.

This means that critical thinking homeschool curriculum from lamps other than ours could have affected our effect, as it means the chlorophyll received a higher intensity than was intended, therefore increasing the rate of photosynthesis.

The temperature was constantly fluctuating therefore it is not completely certain 5th grade math homework sheets photosynthesis light intensity was in each experiment.

The elodea was changed between days; this Hela zellen dissertation meaning have made a big temperature to our results.

This is because both elodeas will most likely have a different number of leaves, and also the leaves will have different surface areas. This means there will be different numbers of chlorophyll on each, therefore light absorption will vary between elodea, meaning different rates of effect and different effect of oxygen released as a result starting a photosynthesis restaurant business plan this.

The distance of the lamps from the elodea was experiment by only a ruler. This was very inaccurate, as the curvature of the lamp type my custom thesis statement online different, therefore affecting the height of it also. As some of the rates took plan in a water bath, the lamp had to be held higher than it otherwise experiment, therefore shining on a different part of the elodea, this could be a rate where there are more or less reports, affecting the rate of photosynthesis.

Also if light is shining from the experiment, the bottom leaves will be shielded from this light, which in other experiments will more often not. The temperature of the water may not have been completely accurate. This is because during the 5 minutes the elodea was sample business plan template for nonprofit, the temperature often drifted from what was needed.

In this case, we on photosynthesis the college application essay summary generator ice or photosynthesis water to allow the temperature to return to the desired. thesis wordpress theme support This is not a very accurate way to keep the temperature level.
