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. White pigments reflect most of the wavelengths striking them.

Detailed explanation-2: -Chlorophyll a absorbs violet and orange light the most. Chlorophyll b absorbs mostly blue and yellow light. They both also absorb light of other wavelengths with less intensity.

Detailed explanation-3: -A pigment is a compound that absorbs a particular wavelength of visible light. Chlorophyll is a green pigment contained in thylakoid membranes of chloroplasts that is used in photosynthesis by plants.
