| hypertonic | greater solute concentration |
| hypotonic | lower solute concentration |
| isotonic | equal solute concentration |
| passive transport | movement across the membrane that doesn't use ATP |
| active transport | movement across the membrane that uses ATP |
| diffusion | the random movement of molecules |
| dialysis | divvusion of solutes across a semipermeable membrane |
| osmosis | diffusion of water across a semipermeable membrane |
| facilitated diffusion | process by which GLUCOSE cross the membrane |
| filtration | movement across a semipermeable membrane due to a pressure gradient |
| crenation | what happens to a cell in a hypertonic environment |
| lysis | what may happen to a cell in a hypotonic environment |
| solute | what is dissolved in a solvent |
| solvent | what causes something to be dissolved |
| solution | solute + solvent |
| contractile vacuoles | organelles used by simple organisms to pump out excess water |
| endocytosis | process by which cells take in bulk material |
| exocytosis | process by which cells get rid of bulk material |
| phagocytosis | process by which cells engulf large solids |
| pinocytosis | process by which cells engulf large amounts of water or dissolved substances |
| carrier proteins | needed for both facilitated diffusion AND active transport |
| phospholipids | main component of the Plasma Membrane |
| cholesterol | gives support to the Plasma Membrane |
| marker proteins | label the cell |
| receptor proteins | when a specific substance binds to these a change occurs in the cell |
| channel proteins | create pores in the membrane for certain substances to pass through |
| pumps | general term for carrier proteins involved in active transport |
