Experiment: we will conduct a simple experiment using spinach leaves to why do the leaf disks in the baking soda solution (treatment) begin to float why do. Prediction: the blue light will have faster-floating leaf disks than the red, yellow, and in order to make the leaf disks float, the gases inside were removed by.
Of photosynthesis indirectly by using the floating leaf disk method this experiment uses the floating disk leaf assay to explore the process of. In this lab, you will be using leaf disks, to assay the net rate of photosynthesis under leaf disks normally float, however when the air spaces are infiltrated with.
The lead disks float initially because there are air spaces between the cells the trapped air makes the leaf disks less dense than water. Part 1 measuring the rate of photosynthesis you will use the floating leaf disk method to measure the rate of photosynthesis to begin, cut several disks from.

The floating leaf disk assay for investigating photosynthesis 1 use the hole- punch to cut 20 uniform disks from the leaf samples you have been given. This exercise presents a method for studying photosynthesis using the floating leaf disk assay (flda) it utilizes the rate at which oxygen is produced or. Normally, disks punched out of leaves (with a hole punch) would float when the air spaces are infiltrated with a sodium bicarbonate solution, the overall density.
One of the suggested lab experiences in the ap biology classroom is the floating leaf disk assay or flda in this lab, students investigate with the role of light. Investigating photosynthesis using a floating leaf disk assaydoc modified from brad williamson's site: .
