| A | B |
|---|
| plasma membrane | controls what enters and leaves the cell |
| selectively permeable | allows some things to cross easier than others |
| diffusion | movement of anything from high to low concentration |
| osmosis | movement of water from high to low concentration |
| passive transport | requires no energy |
| active transport | requires energy (ATP) |
| facilitated diffusion | transport proteins help molecules enter the cell from high to low |
| equilibrium | balance |
| hypertonic | higher concentration of solute |
| hypotonic | lower concentration of solute |
| isotonic | equal concentration of solute |
| endocytosis | engulfing of large particles into cell |
| exocytosis | removal of large particles out of cell |
| phagocytosis | engulfing of food (solid) particles into cell |
| pinocytosis | engulfing of liquids into cell |
| osmosis | diffusion of water |
