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: -The green coloration in the leaves of most plants is due to the presence of chlorophyll, a pigment used to absorb energy from the sun.
Detailed explanation-3: -The green pigment is called chlorophyll. The term is derived from a combination of two Greek words – chloros that means ‘green’ and phyllon that means ‘leaf’. Chlorophyll helps in absorption of light from the blue portion of the electromagnetic spectrum.
Detailed explanation-4: -Chlorophyll is the green pigment in plants, algae, and cyanobacteria that is essential for photosynthesis. Its central structure is an aromatic porphyrin or chlorin (reduced porphyrin) ring system with a sequestered magnesium atom.
Detailed explanation-5: -Chlorophyll is a biomolecule responsible for green colour in the plants. Chlorophyll contains 2.68% of magnesium by mass.
