ANSWER

The shape of the cell depends on-

1) Cytoskeleton are protein filaments that give shape and mechanical strength to the cell.

2) The functions done by the cell. For example, red blood cells flow through the blood vessels. They carry oxygen and are round in shape. Muscle cells are spindle-shaped that help in contraction and relaxation.
