Diffusion DiffusionMotion of particle for high concentration To low concentration. This causes many substances to move across a cell membrane but does not require energy.
What is Osmosis? Osmosis is a type of diffusion. The movement of water across a semi permeable membrane. Osmosis is the movement of water through a semi permeable membrane to a higher concentration of solutes .
Passive Transport • When material move from areas of high concentration to low concentration they don’t requires energy. • Examples • Diffusion • Facilitate Diffusion • Osmosis Particles Water
Active Transport • When material move from areas of low concentration to high concentration they requires energy. • Examples • Endocytosis • Exocytosis
Types of Endocytosis • Phagocytosis • Pinocytosis
