c) How is a cell's potential growth affected by its ratio of surface area to volume? As the cell increases in size the volume of the cell increases more rapidly than the surface area which causes a decrease in the cell's ratio of surface area to volume and makes it more difficult for the cell to move needed materials in and waste products out.
of cytoplasm contained within the cell membrane. from the membrane to the center of the cell by diffusion. there must be an adequate ratio between the cellâs surface area and its volume. simplest model of cell shape) gets larger, its volume increases at a different rate than its surface area. In this lab, we will investigate this relationship and how it affects diffusion time. The prime limitation to cell size is the limitation imposed by diffusion. Diffusion is a very slow process. If a cell were 20 cm (~8 inches), it would take days for nutrients to reach its center or for wastes to reach the cell membrane. The cell would quickly starve to death or poison itself with its own wastes. So whatâs the solution, if a cell approaches its maximum size? Itâs time to divide! If cells receive the proper signals, they will divide by mitosis before they become too big. PART 1 In this lab activity, you will use agar cubes as cell models.
