2020/05/15Measure Photosynthesis with Floating Leaves
The leaf disk assay indirectly measures the rate of photosynthesis.
Set up the light source. You can use a lamp or just sunlight.
Place 10 leaf disks into the syringe.
Push out the air from the syringe.
Release the plunger and remove your finger from the syringe opening to release the vacuum.
Fill the cup with baking soda solution up to a depth of about 3 cm.
Start the timer.
Continue the experiment until all of the leaf disks are floating in one of the cups.
How do the light source, light intensity, or color of the light affect the rate of photosynthesis?
