What methods do cells use to increase the surface area …

WebSome plant cells are, in fact, cube-shaped. If the length of one of the cube’s sides is l l, the surface area of the cube will be 6l^2 6l2, and the volume of the cube will be l^3 l3. This … WebThis means that as l l gets bigger, the surface area will increase quickly since it changes with the square of l l. The volume, however, will increase even faster since it changes with the cube of l l. Thus, as a cell gets bigger, its surface-area-to-volume ratio drops. WebSep 16, 2024 · When a cell’s surface area increases, the amount of substances diffusing into the cell increases. As volume and surface area increase, the volume increases faster, so much so that the surface area available to allow substances in halves each time the cell volume doubles.
