Most plants appear green because chlorophyll
A
absorbs green light.
B
absorbs violet light.
C
does not absorb green light.
D
does not absorb violet light.
Explanation: 

Detailed explanation-1: -Green plants are green because they contain a pigment called chlorophyll. 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-2: -They rarely absorb green for its mostly reflected by plant, that makes them green! Long answer : Photosynthesis is the ability of plants to absorb the energy of light, and convert it into energy for the plant. To do this, plants have pigment molecules which absorb the energy of light very well.

Detailed explanation-3: -Chlorophyll. The green pigment in leaves is chlorophyll, which absorbs red and blue light from sunlight. Therefore, the light the leaves reflect is diminished in red and blue and appears green.

Detailed explanation-4: -In conclusion, plant leaves are green because green light is less efficiently absorbed by chlorophylls a and b than red or blue light, and therefore green light has a higher probability to become diffusely reflected from cell walls than red or blue light.
