NEET BIOLOGY

Detailed explanation-1: -All plants, algae, and cyanobacteria which photosynthesize contain chlorophyll “a". A second kind of chlorophyll is chlorophyll “b", which occurs only in “green algae” and in the plants.

Detailed explanation-2: -Most photosynthetic organisms have a variety of different pigments, so they can absorb energy from a wide range of wavelengths.

Detailed explanation-3: -Green algae are organisms which are characterized by having chlorophylls a and b as the major photosynthetic pigments, starch located within the chloroplast as the major storage product and flagella of the whiplash (smooth) type (e.g., Bold and Wynne, 1985).

Detailed explanation-4: -Hence, chlorophyll a is the pigment that is common to all of the algal classifications.

Detailed explanation-5: -Chlorophyll is a pigment that gives plants their green color, and it helps plants create their own food through photosynthesis.
