By interpolating from … WebNov 25, 2024 · The Floating Leaf Disk Lab replicates AP Biology Investigation 5 by using leaves as a model and observing the release of oxygen gas. We can determine the rate of photosynthesis by measuring how many leaf discs float on a consistent interval. Your knowledge of photosynthesis can be used to answer the questions below to help us …
WebIn the graph, it can be seen that there is a general pattern in which the number of floating plant discs increases as time increases. This is due to the fact that the plant discs are using the CO 2 in the bicarbonate solution they are floating in to conduct photosynthesis, producing oxygen bubbles. WebCount how many disks are floating during each of the next 15 minutes. After all (or most) of the disks are floating, put the cups in the dark (a shoebox or a closet) and monitor for …
WebIn short, the data from the experiment demonstrated that the rate of photosynthesis of leaf disks varied depending on the color of the light source. White light appeared to be the most efficient light source for photosynthesis in spinach leave cells.
