Detailed explanation-1: -The wavelength of green light is thought to be the least efficient for photosynthesis. If the plants are exposed to green wavelengths during photosynthesis, the rate of photosynthesis will be the slowest. This is due to the presence of chlorophyll, a green pigment.

Detailed explanation-2: -The main reason why green light is purportedly not useful to plants is because it is poorly absorbed by chlorophyll.

Detailed explanation-3: -Green light is least absorbed by green leaves, which gives leaves their green appearance (McCree, 1971; Zhen et al., 2019).

Detailed explanation-4: -Because green light can penetrate further into the leaf than red or blue light, in strong white light, any additional green light absorbed by the lower chloroplasts would increase leaf photosynthesis to a greater extent than would additional red or blue light.

Detailed explanation-5: -On an absorbed quantum basis, the efficiency or photosynthetic quantum yield of green light is comparable with that of red light, and greater than that of blue light. The difference between the quantum yields of green and blue light is particularly large in woody plants grown outdoors in high light.
