Diffusion is the movement of particles from an area of high concentration to an area of low concentration.

What is osmosis?
Osmosis is a special form of diffusion which is used to explain the movement of water particles/molecules from an area of high concentrated water (weak/dilute solution) to a area of low water concentration (strong/concentrated solution)

What is active transport?
Active transport is where energy is used to move important minerals against a concentration gradient. (from low to high concentration)
