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: -Complete answer: The colour of the pigment comes from the wavelength of the light they reflect. The green leaves absorb all wavelength except the light of 550nm wavelength, i.e green colour in the visible range. So, the green wavelength is reflected by the plant.

Detailed explanation-3: -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.
