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.
Cell Function. The structural and functional characteristics of different types of cells are determined by the nature of the proteins present. Cells of various types have different functions because cell structure and function are closely related.It is apparent that a cell that is very thin is not well suited for a protective function. Bone cells do not have an appropriate structure for nerve impulse conduction.ust as there are many cell types, there are varied cell functions. The generalized cell functions include movement of substances across the cell membrane, cell division to make new cells, and protein synthesis.
