In plants what absorbs all colors except green?
A
chlorophyll
B
chloroplast
C
ribosomes
D
rough er
Explanation: 

Detailed explanation-1: -Chlorophyll: It is a green pigment present in the leaves of the plant which helps in the process of photosynthesis. Chlorophyll absorbs all colors present in VIBGYOR except the green color. The highest absorption occurs in violet-blue and red regions of visible light.

Detailed explanation-2: -A surface that appears green absorbs all colors except green. White light is a combination of all colors–as is apparent when you shine a white light through a prism–so anything that appears white reflects all wavelengths of light.

Detailed explanation-3: -Chlorophyll, the green pigment common to all photosynthetic cells, absorbs all wavelengths of visible light except green, which it reflects.

Detailed explanation-4: -Chlorophyll b absorbs mostly blue and yellow light. They both also absorb light of other wavelengths with less intensity. However, none of them absorbs green, so the leaf looks green because that light is reflected to our eyes instead of being absorbed by the leaf.

Detailed explanation-5: -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.
