Question

what does the number of floating discs indicate about plant photosynthesis in the floating disc method? the rate of water absorption the rate of oxygen production the rate of sugar consumption the rate of carbon dioxide release

Explanation:

In the floating - disc method for plant photosynthesis, oxygen is produced as a by - product. As oxygen accumulates in the air spaces of the plant discs, they become buoyant and float. So, the number of floating discs is related to the rate of oxygen production during photosynthesis.

Answer:

the rate of oxygen production
