There are permeable and semi-permeable membranes.

The permeable allows any size particle through

The semi-permiable only allows certain particles to go through.

Depending on the concentration gradient as well.

Diffusion is the net movement of particles (atoms, molecules, or ions) from a highly concentratd region to a region of low concentration. Understanding diffusion through a membrane is a key biology concept. Take this interactive tour to help you master the process and terminology.
