Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Chlorophyll is green because
A
it absorbs green wavelengths of light
B
it absorbs blue and yellow wavelengths of light
C
it reflects green wavelengths of light
D
it is an optical illusion caused by the transmission of light
Explanation: 

Detailed explanation-1: -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. Plants that use photosynthesis to make their own food are called autotrophs.

Detailed explanation-2: -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. The molecules of chlorophyll are large (C55H70MgN4O6).

Detailed explanation-3: -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.
