diffusion | The movement of particles from regions of higher density to regions of lower density |
osmosis | The diffusion of water through a semipermeable membrane |
active transport | The movement of substances across a cell membrane that requires the cell to use energy |
endocytosis | The process by which a cell membrane surrounds a particle and encloses the particle in a vesicle to bring the particle into the cell |
