Cellular Movement

3. The shrinking of a cell that occurs when it loses water in a hypertonic solution.
4. A solution where the concentration of water and solutes is the same inside and outside the cell.
9. Refers to the specific proteins on the cell's plasma membrane that bind to molecules during receptor-mediated endocytosis.
10. The process of capturing a substance from outside the cell by engulfing it.
11. The transport of molecules against a concentration gradient, which requires cellular energy
13. Movement of materials across the cell membrane that does not require energy.
15. The movement of molecules from an area of higher concentration to an area of lower concentration.

1. A type of transport where carrier proteins in a plasma membrane help molecules pass across.
2. Also called "cell eating”, it is when the plasma membrane forms a vesicle around a solid particle.
5. Also called "cell drinking" , it is when the plasma membrane encloses small amounts of fluid droplets.
6. A solution where the outside environment has a higher concentration of solute than the cell.
7. The diffusion of water molecules across selectively permeable membranes.
8. A solution with a lower concentration of solute than the cell.
12. The process where a vesicle fuses with the plasma membrane to release its contents outside of the cell.
14. The form of cellular energy required for active transport.
