Detailed explanation-1: -Maximum absorption of light by chlorophyll a occurs in red and blue regions of the absorption spectrum. So that, the rate of photosynthesis is maximum in red and blue light of the visible spectrum. Minimum photosynthesis takes place in the green light.

Detailed explanation-2: -Final answer: Photosynthesis is maximum in red light followed by blue.

Detailed explanation-3: -Chlorophyll a is the primary pigment associated with photosynthesis and it is responsible for entrapping of the sunlight. It shows the highest excitation at the wavelengths of blue and red colour. Thus the maximum photosynthesis observed by plants is in the wavelength of blue and red colour.

Detailed explanation-4: -The light that is absorbed the best is blue, so this shows the highest rate of photosynthesis, after which comes red light. Green light cannot be absorbed by the plant, and thus cannot be used for photosynthesis.

Detailed explanation-5: -Green light drives leaf photosynthesis more efficiently than red light in strong white light: revisiting the enigmatic question of why leaves are green. Plant Cell Physiol.
