Photosynthesis occurs more in blue and red light rays and less, or not at all, in green light rays.

Green Light light is more important for photosynthesis.

As compared to photosynthesis, glucose is chiefly decomposed during Respiration

At the time of a Solar Eclipse, the rate of photosynthesis will: Decrease

In all plants, the major sites of photosynthesis are Leaves

In Photosynthesis reduction occurs in the Water

At night, when photosynthesis is stopped, plants Give off Carbon Dioxide.
