Detailed explanation-1: -Green plants are green because they contain a pigment called chlorophyll. Chlorophyll absorbs certain wavelengths of light within the visible light spectrum.

Detailed explanation-2: -Chlorophyll is a pigment that gives plants their green color, and it helps plants create their own food through photosynthesis.

Detailed explanation-3: -In the case of plants, it is the pigment chlorophyll which absorbs the light, and it is picky about which wavelengths it absorbs – mostly opting for red light, and some blue light.

Detailed explanation-4: -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.
