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.
No, cells arent all the same size. The size of a cell depends on the organism it belongs to and its function, for example a bacterial cell would be a maximum of around 10micro â¦ ns whereas an average human cell is between 10 and 100 microns, with size varying as I said dependant on function.5 people found this useful.he size of a cell depends on the organism it belongs to and its function, for example a bacterial cell would be a maximum of around 10micro â¦ ns whereas an average human cell is between 10 and 100 microns, with size varying as I said dependant on function. 5 people found this useful.
