1. SIMPLE DIFFUSION
Diffusion is the tendency of molecules to spread from regions of high concentration to regions of low concentration. This movement is due to a concentration gradient. This is the difference in concentration between two different regions. An example - when you spray perfume in the corner of a room and eventually you can smell it everywhere.
2. OSMOSIS
Osmosis is the diffusion of water across a selectively permeable membrane from a region of high water concentration to a region of low water concentration.
