The Rate Of Photosynthesis

1) Construct a graph of your data 2) apply the graph, try the time at which 50 percentage of the foliage disks were boasting on the clear. The menstruum at which 50 percent of the leaf disks ar directionless will be you point of reference for future investigations Using the graph the estimated time that roughly 50% of the leaf disks were floating on the surface was around the tenth minute. At the 10th minute our number rose up to 26/50 leaf disks. 3. What inconsistent were you scrutiny in this investigation? We were testing the leaf disks as the control.The albumen calorie-free, and the water were the controlled variables. 4. Explain why the leaf disks started to float after beingness exposed to white light. The leaf disks started floating after being exposed to white light because the do work of photosynthesis is light- dependent. Light is required for the process of photosynthesis to bulge out and so the disks would not start floating unless they were placed under the sun, or in this instance the white light. 6. In this investigation, you careful the treasure of oxygen production. How might you banknote the estimate of privation of carbon dioxide?The rate of oxygen production was measured by the amount of dicks that stated to float at a certain time. After the disks score all floated to the top, the rate of carbon dioxide loss could be measured by how yen it takes for the leaf disks to float back push down to the bottom. 7) Brainstorm possible environmental factors that could profess the rate of photosynthesis. Do research on one of these factors and write a curtly paper on your findings. Factors that could hazard the rate of photosynthesis could be the duration of wavelength, high light intensity, or even air pollutants.The musical theme we researched was racy Light Intensity. High light intensity happens beyond loudness point. Light intensity reduces the rate of photosynthesis. This affect is called solarization. It can be cau sed by photo-inhibition and photo-oxidation. Photo-inhibition and photo-oxidation slip aways when trace leaves are abruptly exposed to glossy light or when sun leaves are exposed to bright light with environmental stresses such as water famine or extreme temperatures. Both occur when the heftiness absorbed by the photosynthetic reaction centers exceeds the ability to use that energy in metabolic activity.
