Document Summary
The typical size of a prokaryotic cell (bacteria and archaea) is ~ 1 - 2 m in length, whereas the typical size of an. Eukaryotic cell (animal and plants) is ~ 5 - 100 m in diameter. The three major factors that limit the cells size include the following: surface area to volume ratio. Surface area: the amount of cell membrane available to import and export from the cytosol. Surface area increases with the square (x2) whereas volume increases with the cube (x3). Therefore large cells have a lower surface area / volume ratio compared to small cells. Cell size can only increase as long as the membrane surface area is adequate for the passage of. Materials into and out of the cell: lowest size limited by, upper size limited by. The minimum number of biomolecules required for the cells existence. The rate of diffusion of solutes in the aqueous intracellular environment.
