Explanation
Chlorophyll is a photoreceptor (light-sensitive) chemical that absorbs light for photosynthesis in plants. It absorbs visible light mainly in the red (long-wavelength) and blue (short-wavelength) regions. Absorption of green light is very low, and green light is reflected. That is why plants appear green.
