The major algae divisions can, for the most part, be drawn based on the algae’s predominant apparent color.

Detailed explanation-2: -They get their green color due to the dominance of pigments chlorophyll a and b. Chlorophyceae are unicellular, colonial, or filamentous. They have a rigid cell wall whose inner layer is made up of cellulose and the outer layer of pectose.

Detailed explanation-3: -Algae are generally grouped according to color. The color is based upon the chlorophyll and other pigments found in the algae cells. Blooms of algae can give the water an unpleasant taste or odor, reduce clarity, and color the water body a vivid green, brown, yellow, or even red, depending on the species of algae.

Detailed explanation-4: -Algae usually are identified with the color green, but they actually occur in a great range of colors and hues, depending on the kind of algae and in some cases on the way they are grown. The colors are due to pigments (colored molecules) within individual cells.
