The exchange of materials occurs between cells and their environment, across the cell membrane. To make this exchange as efficient as possible, some organisms have evolved specialised exchange surfaces like the alveoli in the lungs, or root hairs in plants or the nephrons in kidneys. Depending upon what is being exchanged and which direction along the concentration gradient things are travelling will determine whether diffusion, osmosis or active transport will be used. Diffusion is the process in which particles spread out from each other. They move from high concentration to an area of low concentration,down the concentration gradient until they are evenly distributed. Osmosis is very similar to diffusion but just for water. It is the movement of water into or out of a cell. Again, it is the movement from a dilute solution (so high concentration of water molecules) down the concentration gradient to a more concentrated solution - so low concentration of water molecules. The water molecules move across a partially permeable membrane. Watch part 2 to learn about active transport. SUBSCRIBE to the FuseSchool channel for many more educational videos.
