Osmosis and Diffusion Cells have structures that protect their contents from the world outside.  All cells are surrounded by a cell membrane that separates the cell from  the outside environment. The cell membrane is  selectively permeable Selectively Permeable  -  some substances can pass through the membrane  while others cannot Substances can move into and out of a cell be one of three methods: 1. Diffusion 2. Osmosis 3. Active Transport Diffusion  –  is the process by which molecules move from an area of  higher concentration to an area of lower concentration –  diffusion is the  main method by which small molecules move across the cell membrane!
