Floating disk photosynthesis lab

WebDec 3, 2016 · This lab uses the floating disk leaf assay as a vehicle for exploring the action of photosynthesis in plants. Generally speaking, a leaf floats (due to the many intercellular spaces used for exchange of gases). When these intercellular spaces are instead filled with solution, the density of the leaf increases and it sinks. WebAt any given point in this experiment, the number of floating leaf disks is an indirect measurement of the net rate of photosynthesis. In photosynthesis, plants use energy from the sun, water, and carbon …

WebFloating Disks: An Investigation of Photosynthesis Introduction Plants use the process of photosynthesis to convert light energy into glucose, a carbohydrate that plant cells use for food. Photosynthesis occurs in the chloroplasts of plant cells. For photosynthesis to occur, the energy from the sun needs to be trapped in special molecules. WebThe null hypothesis is that there will be no difference in the rate of photosynthesis, and therefore the number of floating discs, between the bicarbonate and water, or light and dark treatments. To place leaf discs under vacuum, first remove the plungers from two 20 mL syringes, and then place 10 leaf discs inside each syringe tube.
