Question

Minimum photosynthesis takes place in

• A. Green light
• B. Red light
• C. Blue light
• D. White light

Answer 1

The correct option is A Green light

Plants are tolerable to specific wavelengths of light, especially for the photosynthetic reaction. Two major photosynthetic pigments are Chlorophyll A and Chlorophyll B, which absorbs photons from the light and transfer them around to generate chemical energy during the process. Chlorophyll A absorbs a lot of red and some blue light while Chlorophyll B absorbs a lot of blues and some red light. Neither of them absorbs green much which is why plants appear green and minimum photosynthesis takes place in it.

So the correct option is 'green light'.
