Term / Definition
1. / high to low movement of monomers; uses transport protein; no energy required
2. / equal amounts of solute molecules
3. / water-loving
4. / a difference in amount of molecules between two areas
5. / structure that identifies the cell
6. / having less solute molecules than cytoplasm of a cell
7. / allows certain molecules to pass through; keeps some molecules out
8. / the amount of molecules in a specified area
9. / use of vesicles to move polymers out of the cell
10. / substance that is dissolved
11. / outward pressure on cells
12. / movement of molecules from low to high; uses transport protein; requires energy
13. / high to low movement of water; through phospholipid bilayer; no energy required
14. / mixture of a substance that is dissolved in another
15. / movement of molecules from high to low; no energy required
16. / use of vesicles to move polymers into the cell
17. / having more solute molecules than cytoplasm of a cell
18. / structure that consists of 2 layers of lipids
19. / fluid that dissolves a solid, liquid, or gas
20. / water-fearing
21. / high to low movement of small, fat-soluble, uncharged polar molecules; through phospholipid bilayer; no energy required
22. / structure that allows cells to communicate with each other to work as a unit
23. / structure that helps move molecules across the cell membrane
Draw and identify the following structures of the cell membrane: carbohydrate chain, cholesterol, phospholipid bilayer, transport protein
Identify which structures of the cell membrane (phospholipid bilayer, transport protein, vesicle) each type of molecule would travel through.
