bio cell transport
| Question | Answer |
|---|---|
| release of wastes or cell products from inside to outside a cell | exocytosis |
| diffusion of water molecules through a selectively permeable membrane | osmosis |
| loss of water from a cell resolution in a drop of turgor pressure in plants. Plasma membrane detaches from cell wall | plasmolysis |
| continuous movement of particles but no overall change in concentration | equilibrium |
| movement of particles from an area of higher concentration to one of lower concentration | diffusion |
| a solution in which the concentration of dissolved substances is lower than the concentration inside a cell is ___________ | hypotonic |
| the internal pressure of a plant cell is called _________ _______ | turgor pressure |
| in ____________ transport, the movement of particles across a membrane requires energy | active |
| _____________ is a process by which a cell membrane surrounds and takes in material from the environment | endocytosis |
| the passive transport of material across a membrane by means of transport is called _____________ ___________ | facilitated diffusion |
| a membrane that allows only some materials to pass through is called ________ ___________ | selectively permeable |
| the structure most responsible for maintaining cell homeostasis is the | cell membrane |
| a cell membrane is made up of a | lipid bilayer |
| diffusion continues until | equilibrium is reached |
| if a cell is placed in salt water, water leaves the cell by | osmosis |
| if its not watered, a tulip plant wilts because it | looses turgor pressure |
| a cell moves particles from a region of lesser concentration to a region of greater concentration by | active transport |
| when water rushes into the plants cell vacuole, diffusion or osmosis | osmosis |
| is osmosis passive or active transport | passive |
| what is the force called that causes water to rush into the plant cell | osmotic pressure |
| something that gets dissolved | solute |
| substance that dissolves solute | solvent |
| cell shrivels up and dies (plant) | plasmolysis |
| cell bursts (animals) | cytolysis |
| same act of solute inside and outside of the cell | isotonic |
| more solute outside cell than inside | hypertonic |
| more solute inside cell than outside | hypotonic |
