Question

Give an example of algal structure and shapes
​

Answer 1

Answer:

alga are algae in which cells resembling free swimming unicells form groups. They may be large and elaborately interconnected as in Volvox or smaller and relatively simple as in Synura.

Volvox

A Volvox colony is a hollow sphere of mucilage having 500 or more biflagellate algal cells that are equally spaced around on its outer surface.

Synura

They have varied number of ovoid golden brown cells. Each cell bears two flagella, whose beatings propel the colony, through the water with a smooth rolling motion. The individual cells divide longitudinally and the colonies also divide into two, as they grow larger.

Scenedesmus

Scenedesmus is a non motile colonial alga consisting of 2,4 or 8 elongated cells, often with spines on the terminal cells. They are commonly found in ponds and as planktonic forms in rivers and lakes.
