What does diffusion mean?
The movement of particles
osmosis
The diffusion of water through a semipermeable membrane
Passive Transport
The movement of substance across a cell membrane without the use of energy by the cell
active transport
the movement of substance across the cell membrane that requires the cell to use energy
endocytosis
the precess by which a cell membrane surrounds a particle and encloses the particle in a vesicle to bring the particle into the cell
exocytosis
the process in which a cell releases a particle by enclosing the particle in a vesicle that then moves to the cell surface and fuses with the cell membrane
photosynthesis
the process by which plants, algae, and sone bacteria use sunlight, carbon dioxide, and water to make food.
cellular respiration

fermentation
the breakdown of food without the use of oxygen
