The Characteristics of Cells
... Why are most cells small? • Cells are small because their size is limited by their outer surface area. • If cells get too large, they cannot take in enough nutrients or get rid of enough wastes. • The surface area-to-volume ratio of a cell is the ratio of the outer surface to the cell’s volume. The ...
