| "fluid" | Refers to the motions and interactions of component parts of the membrane. |
| phospholipid molecule | consists of a hydrophilic head and two hydrophobic tails. |
| adhesion proteins | Of multicellular organisms; helps cells of the same type locate and stick to one another and stay positioned in the proper tissues. |
| prokaryotic | Bacteria cells lacking a nucleus. |
| transport proteins | Allow water souvle suvstances to move through teir interior, thus crossing the bilayer |
| mosaic | Refers to the mixed composition of diverse phospholipids, glycolipids, sterols, and proteins |
| recognition proteins | Like moecular fingerprints, their oligosaccharide chains identify a cell as being of a specific type |
| fluid mosaic | By this model, membranes have a miced composition of lipids and proteins |
| receptor proteins | Bind extracellular sustances, such as hormones, that trigger changes in cell activities. |
