NEET BIOLOGY

Detailed explanation-1: -Chlorophyll is a pigment that gives plants their green color, and it helps plants create their own food through photosynthesis.

Detailed explanation-2: -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-3: -Chlorophyll is vital for photosynthesis, which allows plants to absorb energy from light. Chlorophyll molecules are arranged in and around photosystems that are embedded in the thylakoid membranes of chloroplasts.

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.
