Lab Report For Photosynthesis Emily Baughman Cecilia Jones November 11th, 2015 Biomedical Sciences Renee Tanner The most important concept in our experiment is the variable that we changed which was the type of leaf. Others are the fact that photosynthesis should have occurred and the leaf disks should have floated over time in the soap and water solution as well as the bicarbonate solution. From our last experiment and other examples of the experiment around 11 minutes there should have been some movement. In the dark solution after removal from under the light after 14 minutes it was to show how stored energy from the photosynthesis process should have kept the disks floating. We hope to learn how the effect of having different leaves will have on this experiment. Independent Variables: Intensity of light Dependent Variables: Time it takes for disks to float Constants: Volume of solution Type of leaves Presence of CO2 Size of leaf discs Temperature Our hypothesis is that it will take more time for the disks to rise than the spinach leaves from the original experiment. The reason we think so is because the amount of light the plant receives coupled with the amount of available CO2 will influence the rate at which photosynthesis occurs. Meaning with the light available and the amount of baking soda we add would affect the spinach more so that the shrub leaves we will use.
