10. Helps with adhesion to other cells
12. contains hydrophilic and hydrophobic regions
13. The process by which water travels to a more negative water potential via a partially permeable membrane.
14. Act as receptors for molecules such as hormones
15. the cell membrane is said to be partially _______
16. A carbohydrate chain attached to a protein within the membrane
17. Diffusion mediated by channel proteins which does not require energy.

1. Describes a non polar molecule that does not readily associate with water through hydrogen bonds
2. A phospholipid with a carbohydrate chain attached
3. Describes a polar molecule that selectively associates itself with water through hydrogen bonds
4. A membrane protein that spans the lipid bilayer having portions in contact with both the inside and outside of the cell
5. The are surrounding the cell membrane
6. The hydrophilic region of the bilayer
7. The principal design of the plasma membrane consists of two layers; what name is given to these two layers?
8. The hydrophobic region of the bilayer
9. Limits fluidity of the membrane
11. A protein responsible for mediating the passive transport of molecules by facilitated diffusion from one side of the lipid bi
