A level diffusion
WebA-level Biology – Transport Across Membranes: Diffusion Membrane Thickness The membrane has to be very thin. The membrane has to be thin in order to provide the shortest path length, or distance for the substances to diffuse across. There is an upper limit on cell size. This size limit on the membrane places an upper limit on the size of the cell. WebDiffusion is the net movement of molecules from an area where they are at a higher concentration to areas where they are at a lower concentration. This is due to the …

WebDiffusion is the process of movement of molecules under a concentration gradient. It is an important process occurring in all living beings. Diffusion helps in the movement of substances in and out of the cells. The molecules move from a region of higher concentration to a region of lower concentration until the concentration becomes equal ...
