Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration. Osmosis is the movement of water molecules across a cell’s membrane. These two procedures help a cell to survive because they help maintain homestasis. (Diffusion) Homestasis is the steady or balanced state of a cell. (Diffusion) Therefore it is important to find what conditions will
