| osmosis | diffusion of water across selectively permeable membrane |
| channel protein | a tubelike passageway that allows specific molecules to flow through |
| facilitated diffusion | passive transport of materials across membrane using transport proteins |
| carrier proteins | change shape to allow a substance to pass through plasma membrane |
| active transport | movement of materials through a membrane against concentration gradient using energy |
| hypertonic | concentration of solutes outside the cell higher than inside the cell |
| exocytosis | expulsion or secretion of large materials from a cell |
| passive transport | movement of materials across plasma membrane with the concentration gradient using no energy |
| endocytosis | process in which cells engulf large particles |
| isotonic solution | concentration of solutes the same outside and inside the cell |
| diffusion | net movement of particles from an area of high to low concentration |
| hypotonic solution | concentration of solutes is lower outside the cell than inside |
| shrinks or shrivels | animal cell placed in hypertonic solution |
| swells or bursts | animal cell placed in hypotonic solution |
| high turgur pressure | plant cell in hypotonic solution |
| low turgor pressure | plant cell in hypertonic solution |
