osmosis/diffusion
| Term | Definition |
|---|---|
| the pressure inside a plant cell caused by water pushing against the cell wall | turgor pressure |
| swelling and buursting of animal cells when water enters | cytolysis |
| cause of increasing osmotic pressure | plant cells in a hypotonic solution |
| shrinking of plant cells when water leaves | plasmolysis (plant) |
| shrinking of animal cell in a hypertonic solution | plasmolysis (animal) |
| when the concentration of a solute is the same throughout a system | equilibrium |
| the diffusion of water across a selectively permeable membrane | osmosis |
| energy for active transport | mitochondria |
| white blood cells engulf. digest, and destroy invading bacteria | phagocytosis |
| proteins that help in facilitated diffusion | integral |
| endocytosis that brings in small dissolved molecules (solutes) and fluids | pinocytosis |
| what golgi bodies use to transport molecules out of cells | exocytosis |
| pressure exerted by water moving during osmosis | osmotic pressure |
| molecule that provides energy for active transport | ATP |
| cell organelle that burns glucose and provides ATP for active transport | mitochondria |
| small membrane sac used to transport substances during exocytosis & endocytosis | vesicle |
| carrier proteins grab glucose molecules, change shape, and flip to the other side of the membrane | during facilitated diffusion |
| integral membrane protein that helps move molecules across a cell membrane | channel protein |
| forms whenever there is a difference in concentration between one place and nother | concentration gradient |
| two kinds of endocytosis | pinocytosis and phagocytosis |
| Ca**, H*, Na*, and K* move across membranes with | ion channels |
| passive transport of gases across cell membrane | diffusion |
| glucose enters cell most rapidly by what | facilitated diffusion |
| transport of substances using energy | endocytosis |
