DENDROLOGY

Detailed explanation-1: -The process of photosynthesis produces oxygen, which is released by the plant into the air. Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green.

Detailed explanation-2: -In the case of plants, it is the pigment chlorophyll which absorbs the light, and it is picky about which wavelengths it absorbs – mostly opting for red light, and some blue light.

Detailed explanation-3: -Leaves are green in colour because of the presence of green colour pigments within the plant cell called chlorophyll.
