\nGreen plants appear green because they reflect or transmit green light rather than absorbing it significantly for photosynthesis.
\n<\/section>\n
\n– Photosynthesis primarily utilizes light from the blue and red ends of the visible spectrum, as chlorophyll pigments absorb these wavelengths most effectively.
\n– Green light is poorly absorbed by chlorophyll, hence it is reflected or transmitted, making the plants appear green.
\n<\/section>\n
\nThe absorption spectrum of chlorophyll a and chlorophyll b shows peaks in the blue-violet and red regions, with a dip in the green region. While some green light is absorbed by accessory pigments like carotenoids, the overall absorption is lowest for green light compared to other colours essential for photosynthesis.
