NEET BIOLOGY

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: -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-3: -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-4: -11.3. Chlorophyll is the major pigment used by plants for capturing light energy. A chlorophyll molecule consists of a porphyrin head (four pyrrole rings containing nitrogen arranged in a ring around a magnesium ion) and a long hydrocarbon tail. The hydrocarbon tail is lipid-soluble.

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.
