Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which color is not used by the chlorophyll pigments (I.e., which color is reflected and not absorbed)?
A
green
B
blue
C
yellow
D
red
Explanation: 

Detailed explanation-1: -Chlorophylls do not absorb wavelengths of green and yellow, which is indicated by a very low degree of light absorption from about 500 to 600 nm.

Detailed explanation-2: -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.

Detailed explanation-3: -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-4: -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-5: -Answer and Explanation: Chlorophyll reflects green light, which is what makes most plants, especially their leaves, appear green in color. It absorbs light along the red and blue wavelengths spectrum. By absorbing these, it converts sunlight into energy for the plant.
