3. regulates what enters and leaves the cell
6. double layer of protein on the core of cell membrane
7. movement of specific molecules across cell membrans through protein channels
9. diffusion of water through selectively permeable membrane
10. the mass of solute in a given volume of solution
16. process by which a cell takes material into the cell by infolding of the cell membrane

1. strong protected layer around the cell membrane
2. energy requiring process that moves material across a cell membrane
4. process by which molecules move from an area that is more concentrated to less concentrated
5. extensions of cytoplasm surround and engulf large particle and take them into the cell
8. when the concentration of two solution is the same
11. when the concentration of a solute is the same throughout a solution
12. when comparing two solutions the solution with greater concentration of solute
13. process by which a cell takes in lipid from the surrounding enviroment
14. process by which a cell releases large amounts of material
15. when comparing two solutions the solution with greater concentration of solute
