Answer :

A plant needs water, sunlight, and carbon dioxide for photosynthesis. The products of photosynthesis are oxygen and glucose. A by-product of photosynthesis is water. Photosynthesis occurs in the chloroplasts of plant cells.

The hypothesis for this experiment is that light intensity affects the rate of photosynthesis. The control group is the syringe without the light bulb. The variables tested in this experiment are light intensity and the type of solution.

The syringe with the light bulb had the most leaf disks floating after 20 minutes. There were no syringes without floating disks. The number of floating disks corresponds to the rate of photosynthesis.

According to the data, light intensity does affect the rate of photosynthesis. The baking soda solution did not affect photosynthetic rates. Photosynthesis is a light-dependent reaction because it needs light to produce oxygen gas.
