| Term | Definition |
|---|
| diffusion | ONLY happens to water, it goes across a semipermeable membrane |
| Osmosis | Molecules move from high to low concentration due to random movement of anykind of molecules, no mb needed (passive) (ex. skunk smell) |
| Passive transport | No energy needed, it goes down the concentration gradient |
| Active transport | requires energy , goes against the concentration gradient |
| concentration | the strength of a solution |
| solution | Made up of a solvent (usually water) and a solute |
| solute | the dissolved substance in a solution |
| solvent | Does the dissolving of other substances |
| isotonic | concentrations are equal (no net movement or water) |
| hypertonic | more solutes, less water |
| hypotonic | less solutes, more water |
| permeable | allowing (especially liquids) to pass or diffuse through |
| osmoregulation | The control of water balance in organisms living in hypertonic, hypotonic, or terrestrial environments. |
| cyclosis | the circulation of cytoplasm within a cell |
| endosymbiotic theory | theory that eukaryotic cells formed from a symbiosis among several different prokaryotic organisms |
| facilitated diffusion | movement of specific molecules across cell membranes through protein channels |
| Phospholipid | special type of lipid(fat) (cell that forms most of the cell membrane) |
| hydrophobic | Repelling, tending not to combine with, or incapable of dissolving in water. |
| hydrophilic | Likes water, Can combine with water and dissolve it |
| Transport protein | A transmembrane protein that helps a certain substance or class of closely related substances to cross the membrane. |
