WebDo you know where the oxygen you breathe comes from? It is produced by plants during photosynthesis! Photosynthesis is a process that plants use to convert sunlight into energy for themselves... WebProcedure 2: Observation of O2 Production in Photosynthesis This experiment uses a floating disk leaf assay to explore the process of photosynthesis in plants. Leaf disks generally float due to the many intercellular spaces used for exchange of gases.

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. http://www.bozemanscience.com/photosynthesis-lab-walkthrough population effect on economy

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 … WebThe TIME at which 50% of the leaf disks are floating (the median) is called the ET 50 (Estimated Time 50%). By interpolating on the graph (Figure 2), the 50% floating point is about 11.5 minutes. (Data show that, when comparing factors that affect the rate of photosynthesis, using the 50% point provides a greater degree of reliability and ...
