Ã¯Â»Â¿The Rate Of Photosynthesis: Lab report
1) Construct a graph of your data2) Using the graph, estimate the time at which 50 pct of the sky disks were fuck uping on the surface. The point at which 50 percentage of the flip disks are floating will be you point of savoir-faire 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 variable were you testing in this investigation?We were testing the leaf disks as the control. The white light, and the water were the controlled variables. 4. Explain why the leaf disks started to float subsequently beingness exposed to white light. The leaf disks started floating after being exposed to white light because the subprogram of photosynthesis is light- dependent. swinging is required for the process of photosynthesis to begin and so the disks would not start floating unless they were placed down the stairs the su nlight, or in this instance the white light.In this investigation, you measured the charge per unit of atomic number 8 production. How might you measure the rate of loss of ampere-second dioxide? The rate of type O production was measured by the amount of dicks that stated to float at a certain time. After the disks have all floated to the top, the rate of carbon dioxide loss could be measured by how long it takes for the leaf disks to float back down to the bottom. 7) Brainstorm possible environmental factors that could affect the rate of photosynthesis. Do research on one of these factors and write a niggling paper on your findings. Factors that could affect the rate of photosynthesis could be the duration of wavelength, full(prenominal) light intensity, or even air pollutants.The topic we researched was High unhorse Intensity. High light intensity happens beyond saturation point. Light intensity reduces the rate of photosynthesis. This affect is called solarization. It can be caused by photo-inhibition and photo-oxidation. Photo-inhibition and photo-oxidation occurs when step leaves are abruptly exposed to bright light or when sun leaves are exposed to bright light with environmental stresses such as water deficit or extremetemperatures. Both occur when the cipher absorbed by the photosynthetic reaction centers exceeds the ability to use that muscularity in metabolic activity.
