All cells are bound by some type of permeable or semipermeable membrane that governs the ions, small molecules, and large molecules that enter and leave the cell. Diffusion is the general process of movement down a gradient that results in equal concentrations of solutes on both sides of the membrane. When water is the molecule entering or leaving the cell the process is osmosis. This guide breaks down the important information students need to know, provides links to products and free digital resources, and includes suggestions for hands-on-labs that reinforce student learning.
