| 210131053 | hypotonic | having a lower concentration of solute than another solution, water moves OUT | |
| 210131054 | hypertonic | having a higher concentration of solute than another solution, water moves IN | |
| 210131055 | osmotic pressure | pressure required to prevent water from entering a hypertonic solution | |
| 210131056 | water potential | pressure potential(+/-) plus solute potential (-), equal to zero at equilibrium | |
| 210131057 | crenate | animal cells shrivel up in a hypERtonic solution | |
| 210131058 | lyse | animal cells explode in a hypOtonic solution | |
| 210131059 | plasmolyze | plant cells contents shrink and pull away from its cell wall in a hypERtonic solution | |
| 210131060 | turgor pressure | the pressure that water molecules exert against the cell wall in a hypOtonic solution | |
| 210131061 | contractile vacuole | The cell structure that collects extra water from the cytoplasm and then expels it from the cell | |
| 210131062 | facilitated diffusion | speeds up rate of diffusion using integral proteins, substrate specific transport proteins, no ATP, moves material down gradient (ex.aquaporins, gated channels) | |
| 210131063 | active transport | moves material from low to high concentration, uses ATP, substrate specific transport proteins, uses integral proteins (ex. NA+/K+ pump, H+ pump) | |
| 210131064 | sodium potassium pump | uses electrochemical gradient with high concentration Na on outside of cell and low concentration K on inside to create membrane potential difference in charge so ions can diffuse down gradient | |
| 210131065 | hydrogen pump | uses electrochemical gradient to move low concentration H+ ions from the cell using energy harnessed from membrane potential | |
| 210131066 | membrane potential | difference in charge across membrane | |
| 210131067 | electrochemical gradient | concentration difference in ions | |
| 212132695 | bulk transport | movement of large materials in and out of the cell, requires energy | |
| 212170463 | endocytosis | materials enter the cell by creating a pod out of membrane to be stored in | |
| 212170464 | exocytosis | materials leave the cell through a vacuole that becomes part of the cell membrane | |
| 212170465 | phagocytosis | pseudopod engulfs food from outside and puts it in food vacuole "cell eating" | |
| 212170466 | pinocytosis | cell membrane pinches off vesicles into the cell "cell drinking", process by which a cell takes in liquid from the surrounding environment | |
| 212170467 | receptor mediated endocytosis | allows the cell to acquire bulk quantities of specific substrates by receptors to which substrates attach which are then engulfed by the cell |
