Detailed explanation-1: -The shapes of cells usually relate to their function. The neurons in our brains, for instance, have star-like branches to network with other neurons, and red blood cells have the form of biconcave discs to maximise their oxygen-carrying capacity while allowing them to squeeze through the narrowest blood vessels.

Detailed explanation-2: -Cell shape is largely determined by the cooperative dynamics of the actomyosin cytoskeleton, adhesions and the cell membrane within the motile appendages at the cell periphery, so the fine-scale geometry of these appendages plays an important role in cell-shape determination.

Detailed explanation-3: -Generally, cells are round, spherical or elongated. Some cells are long and pointed at both ends. They exhibit a spindle shape. Cells sometimes are quite long.

Detailed explanation-4: -Usually, the cells are round, elongated or spherical. There are also some cells which are long and pointed on both the ends. Such cells exhibit spindle shape.
