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: -Chlorophylls. The chlorophylls, a and b, are the pigments of photosynthesis. They are produced in chloroplasts in the photosynthetic tissues of the leaf. The chlorophyll molecules are very water repelling, partly because of the long phytol tail in the molecule.

Detailed explanation-3: -This pigment itself absorbs maximum radiation at the blue and red region. So, Chlorophyll a is the chief pigment of photosynthesis and others (i.e., chlorophyll-b, xanthophyll and carotenoids) are accessory pigments.

Detailed explanation-4: -Chlorophyll A is the primary pigment of photosynthesis, trapping the light energy and emitting highenergy electrons into the two photosystems P680 and P700. Chlorophyll B is the accessory pigment, passing the trapped energy into chlorophyll A.

Detailed explanation-5: -Chlorophylls are greenish pigments which contain a porphyrin ring. This is a stable ring-shaped molecule around which electrons are free to migrate.
