| Cell Membrane | a flexible structure that forms the outer boundary of the cell |
| Cell membrane contains | protein and lipids |
| lipid bilayer | 2 layers of lipids |
| Lipids in membrane is called | Phospholipids |
| outside of bilayer | hydrophilic |
| inside of bilayer | hydrophobic |
| Polar is a | charged molecule |
| nonpolar is a | uncharged molecule |
| polar molecules attract | other polar molecules |
| nonpolar molecules attract | other nonpolar molecules |
| water is attracted to | phospo |
| protein go through the | bilayer |
| defenition of osmosis | diffusion of water |
| Hypertonic solution | higher concentraction of solute and a lower concentraction of water |
| Hypotonic solution | low solute higher concentraction of water |
| isotonic solution | same concentraction in and out of cell |
| hypertonic solution means | more water inside that means water will move outside and cell will shrivel |
| hypotonic solution means | more water outside the cell and it will move inside the cell and cell could pop |
