diffusion
the net movement of particles from a region of their higher concentration to a region of their lower concentration (i.e. down a concentration. gradient), as a result of their random movement
osmosis
the net movement of water molecules from a region of higher water potential to a region of lower water potential, through a partially permeable membrane
osmosis in animal cells
Increasing solute concentration inside of cell can cause cell to explode as a result of it having too much water, crenation.
osmosis in plant cells
Increasing solute concentration inside of cell causes cell to become turgid.
active transport
Movement of particles through a cell membrane, from a region of lower concentration to a region of higher concentration against a concentration gradient, using energy released during respiration
