Floating disk photosynthesis lab
http://athensmutualaid.net/floating-leaf-disk-photosynthesis-lab-answers/ 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.

WebDec 9, 2024 · A floating leaf disk assay is a process for analyzing floating leaves. This procedure can be used to determine which factors affect the rate of photosynthesis during this plant biology project. This lab replicates AP Biology Investigation 5 by examining the rate of photosynthesis as a result of the release of oxygen gas from leaves. 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.
