Cellular Transport
Movement of things in the cell
| Question | Answer |
|---|---|
| maintaining balance or stable internal conditions | homeostasis |
| cell organelle that maintains balance in cell by allowing certain things to enter and leave the cell | cell membrane |
| transport that requires energy (ATP) to move things from low to high concentration area | active transport |
| transport that DOES not need energy to move things from high to low concentration area | passive transport |
| movement of anything EXCEPT water from high to low | diffusion |
| movement of Water Only from high to low | osmosis |
| active transport of materials OUT of the cell | exocytosis |
| active transport of materials INTO the cell | endocytosis |
| movement of large particles from high to low with the help of protein channels or gates | facilitated diffusion |
| happens to cell size in an isotonic solution | stays the same |
| happens to cell size in a hypertonic solution | it shrinks (gets smaller) |
| happens to cell size in a hypotonic solution | it swells (gets larger) |
