Content: Light: A study of the effect of light on the rate and quantity of photosynthesis would have to include light reflected, absorbed and transmitted; intensity, quality and duration of available light, and destructive effects of light. The plant is capable of using only a very small portion of the incident electromagnetic radiation that falls on a leaf. This radiation is absorbed by the pigment complex of the leaf. ADVERTISEMENTS: Each pigment has its own absorption spectrum. The chlorophylls absorb heavily in the blue and red region of the spectrum and β-carotene mostly in the blue region. Most of the light is being reflected in the green region, giving a leaf the green colour. The greater absorption of light is found in thicker leaves with, a lower percentage of transmitted light as compared to thinner leaves.
