How do floating disks correspond to the rate of photosynthesis?

The floating disks corresponds with the solution of carbon dioxide and also the light. when carbon dioxide solution and light is present, the leaf disks react and start floating on the surface. The leaf disk will still rise to the surface if there is only carbon dioxide but in the presence of light it will take less time and if no light it will take much longer.

Glucose, also called grape sugar, blood sugar or corn sugar, is among the simplest and one of the primary naturally occurring sugars. produced naturally by plants as the primary photosynthesis product, it is heavily used by living beings as a main energy source and is necessary for cellular respiration. chemically, it is a monosaccharide carbohydrate and serves as a building block for complex sugars like starch.
