| Term | Definition |
|---|
| passive transport | the movement of substances across a cell membrane without the use of energy by the cell |
| diffusion | movement of particles from an area of high concentration to an area of lower concentration |
| equilibrium | the concentration of molecules will be the same throughout the space the molecules occupy |
| osmosis | diffusion of water |
| hypotonic | describes a solution whose solute concentration is lower than the solute concentration inside a cell |
| hypertonic | when the concentration of solute molecules outside the cell is higher than the concentration in the cytosol |
| isotonic | when the concentration of two solutions is the same |
| contractile vacuoles | organelles that remove water |
| turgor pressure | the pressure that water molecules exert against the cell wall |
| plasmolysis | shrinking of cytoplasm caused by the loss of water |
| cytolysis | The bursting of cells |
| facilitated diffusion | the transport of substances through a cell membrane along a concentration gradient with the aid of carrier proteins |
| carrier proteins | a protein that transports substances across a cell membrane |
| ion channels | pore in cell membrane through which ions move |
