NEET BIOLOGY

Detailed explanation-1: -Carotenoids are ubiquitous and essential pigments in photosynthesis. They absorb in the blue-green region of the solar spectrum and transfer the absorbed energy to (bacterio-)chlorophylls, and so expand the wavelength range of light that is able to drive photosynthesis.

Detailed explanation-2: -Carotenoids are another key group of pigments that absorb violet and blue-green light (see spectrum graph above).

Detailed explanation-3: -Carotenoids absorb light in the blue-green and violet region and reflect the longer yellow, red, and orange wavelengths; these pigments also dispose excess energy out of the cell.

Detailed explanation-4: -Another pigment found in the leaves of many plants is carotene. Carotene absorbs blue-green and blue light. The light reflected from carotene appears yellow.

Detailed explanation-5: -Some of those other pigments are called carotenoids. They absorb green light and reflect orange. Carrots have a lot of carotenoids. During the summer, there is so much chlorophyll in the leaves we simply cannot see the other pigments.
