Plant photosynthesis has the lowest utilization rate of green light. This is related to photosynthetic pigments. Chlorophyll mainly absorbs blue-violet light and red light, while carotenoids absorb blue-violet light, so the utilization rate of green light is the lowest.

Photosynthetic pigments are pigments that participate in the absorption and transmission of light energy or cause primary photochemical reactions in photosynthesis. Photosynthetic pigments exist in chloroplast thylakoid membrane, including chlorophyll, reaction center pigment and accessory pigments.

Extended data

Chlorophyll is the main pigment of photosynthesis in plants, and it is a kind of pigment family containing lipids, which is located on thylakoid membrane and gives plants green. The light absorbed by chlorophyll is mainly blue-purple and red, not green light. The amount of absorbed green light is small, so chlorophyll is green. ) plays a central role in the light absorption of photosynthesis.

Carotenoids are compounds with 8 isoprene units and 40 carbon atoms, which are insoluble in water but soluble in organic solvents. Carotenoids in chloroplasts contain two pigments, namely carotene and lutein, the former is orange and the latter is yellow. Generally speaking, the ratio of chlorophyll to carotenoids in leaves is about 3: 1, so normal leaves are green.
