Diffusion Across a Cell Membrane. Diffusion is the movement of a substance across a membrane. Substances diffuse across cell membranes in a process known as passive transport. This means that the cell does not expend any energy in transporting substances across the cell membrane.
Diffusion is driven by the random movements of individual molecules in solution. If the concentration of a molecule is greater outside a cell than inside the cell then, on average, more molecules will randomly enter the cell, than leave the cell.
