Most cells are small for two main reasons: a). The cellâs nucleus can only control a certain volume of active cytoplasm. b). Cells are limited in size by their surface area to volume ratio. A group of small cells has a. relatively larger surface area than a single large cell of the same volume. This is important. because the nutrients, oxygen, and other materials a cell requires must enter through it surface. As a. cell grows larger at some point its surface area becomes too small to allow these materials to enter. the cell quickly enough to meet the cell's need.
