The Floating Leaf Disk Assay for Investigating Photosynthesis
cpb-us-e1.wpmucdn.comleaf disks into the syringe barrel. Replace the plunger being careful not to crush the leaf disks. Push on the plunger until only a small volume of air and leaf disk remain in the barrel (< 10%). • Pull a small volume of sodium bicarbonate solution into the syringe. Tap the syringe to suspend the leaf disks in the solution.
Floating Leaf Disks for Investigating Photosynthesis v2
photosynthesis.org.auto use the technique to answer their own questions about photosynthesis. How it works: Leaf disks float, normally. When the air spaces are replaced with water the overall density of the leaf disk increases and the disk sinks. ... Microsoft Word - Floating Leaf Disks for Investigating Photosynthesis v2

labsci.stanford.eduheavier, and the leaf sinks. This experiment takes advantage of the fact that when oxygen leaves the Light Reactions chain, it gets trapped in the inner spaces of the leaf So as photosynthesis takes place in the leaf disk, tiny oxygen bubbles will push out the solution from the leaf spaces and make the leaf disks light enough to rise.
