DENDROLOGY

Detailed explanation-1: -Chlorophyll, the green pigment common to all photosynthetic cells, absorbs all wavelengths of visible light except green, which it reflects. This is why plants appear green to us. Black pigments absorb all wavelengths of visible light that strike them.

Detailed explanation-2: -Chlorophyll absorbs certain wavelengths of light within the visible light spectrum. Chlorophyll absorbs red and blue light. Green light is not absorbed but reflected, making the plant appear green.

Detailed explanation-3: -The simple answer is that although plants absorb almost all the photons in the red and blue regions of the light spectrum, they absorb only about 90% of the green photons. If they absorbed more, they would look black to our eyes. Plants are green because the small amount of light they reflect is that color.
