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.

Detailed explanation-2: -The chlorophyll molecule consists of a central magnesium atom surrounded by a nitrogen-containing structure called a porphyrin ring; attached to the ring is a long carbon–hydrogen side chain, known as a phytol chain. Variations are due to minor modifications of certain side groups.

Detailed explanation-3: -What makes a leaf green is chlorophyll, the green pigment located within the chloroplasts. More specifically, chlorophyll resides in the thylakoid membranes. The chlorophyll absorbs energy from sunlight, and it is this energy that drives the synthesis of food molecules in the chloroplast.

Detailed explanation-4: -Plants and green algae (plants are really advanced green algae) contain chlorophyll a (which is teal-green), chlorophyll b (which is yellow-green), and beta-carotene (which is yellow), thus giving them a green color.

Detailed explanation-5: -Chlorophyll a is the most abundant form in leaves and has a light green colour. Chlorophyll b absorbs more of the shorter, blue wavelengths of sunlight, giving it a darker shade of green. It is known as an accessory pigment because its role is to pass light energy to chlorophyll a to complete the photosynthesis.
