Floating disk photosynthesis lab
WebWhen the air spaces are infiltrated with a solution the overall density of the leaf disk increases and the disk sinks. The infiltration solution includes a small amount of sodium bicarbonate (NaHCO 3) thus enabling the bicarbonate ion to serve as the carbon source for photosynthesis.

WebDec 7, 2024 · In the floating leaves lab, students test the rate of photosynthesis by measuring the production of oxygen gas over time. This lab is often used to introduce … 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.
WebFloating disks correspond to the photosynthetic rate because when more disks float it shows that the photosynthesis is occurring. Also, if the disks rise faster it shows that … 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.
