Question

What determines shape and size of a cell?​

Answer 1

The total surface area of a cell is just sufficient for its inner content. Any increase in the surface area produces manifold increase of the cell volume which upsets the balance. Thus the particular shape and size which a cell attains are determined by the ratio of surface area and inner volume.

Answer 2

Answer:

Cell size is limited by a cell's surface area to volume ratio. A smaller cell is more effective and transporting materials, including waste products, than a larger cell. Cells come in many different shapes. A cell's function is determined, in part, by its shape.
