WebNov 19, 2024 · A floating leaf indicates that photosynthesis is occurring because the plant is using the sunlight to convert carbon dioxide into oxygen. The oxygen is then released into the water, which makes the leaf float. An experiment to measure photosynthesis with floating leaves was performed. 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.
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 ... WebInvestigating Photosynthesis and Respiration 1.
