Surface area is the amount of cell membrane available for diffusion. So for a cell, surface area actually represents how much diffusion that can happen at one time. Whereas volume is the amount of cytoplasm contained within the cell membrane.So for a cell, volume is how long It takes to get from the membrane to the center of the cell by diffusion. Therefore, to perform diffusion efficiently, there must be an adequate ratio between the cellâs surface area and its volume.o for a cell, surface area actually represents how much diffusion that can happen at one time. Whereas volume is the amount of cytoplasm contained within the cell membrane. So for a cell, volume is how long It takes to get from the membrane to the center of the cell by diffusion.
Cell Membranes: Diffusion and Osmosis Part 1: Diffusion Diffusion is a process by which molecules move into or out of cells. To diffuse into or out of a cell, molecules must pass through the cell membrane. Observing the diffusion process in real cells is difficult because they are too small to be seen easily.
