WebThus, as the radius of a cell increases, its surface area increases as the square of its radius, but its volume increases as the cube of its radius (much more rapidly). Therefore, as a cell increases in size, its surface area-to-volume ratio decreases. This same principle would apply if the cell had the shape of a cube, as in the figure below. WebAlthough increasing the size of a cell would increase its surface area, it would also increase the cells volume and thus its demand for nutrients etc. In fact, increasing the size of the cell has a much greater effect on the cells volume than it does on its surface area. fix for leaking gutter cornersWebJan 10, 2024 · Eukaryotic cells are compartmentalized which is a method to increase the surface area as there are lots of membranes inside the cell across which many processes take place.
