| Hypotonic | -A hypotonic solution is one in which the concentration of solutes is greater inside the cell than outside of it. -Water enters the cell and causes it to swell/possibly burst. |
| Hypertonic | -A hypertonic solution is one where the concentration of solutes is greater outside the cell than inside it. -Water leaves the cell causing it to shrivel |
| Facilitated Diffusion | The passive movement of molecules across the cell membrane via the aid of a protein channel. |
| Active Transport | Active transport uses energy to move molecules against a concentration difference. |
| Passive Transport | The movement of materials across a cell membrane without requiring energy. |
| Turgor Pressure | -The force within the cell that pushes the plasma membrane against the cell wall. -The water pressure inside of a plant, maintained through osmosis. |
| Endocytosis | The process of taking material into the cell by means of infoldings (pockets) |
| Exocytosis | The membrane of a vesicle surrounds the material then fuses within the cell membrane, contents are pushed out of the cell. |
| Pinocytosis | Tiny pockets fom along the cell membrane, fill with liquid, and pinch off to form vacuoles within the cell. -A type of endocytosis. |
| Phagocytosis | Extensions of cytoplasm surround a particle and package it within a food vacuole, then cell engulfs it. How amoebas take in food, and how white blood cells eat damaged cells. Takes lots of energy, active transport. |
| Permeable | -Capable of being permeated or passed through, used especially of substances where fluids can penetrate or pass through. -Wood is permeable to oil. |
| Impermeable | Something that is impermeable does not allow water or liquid to pass through it. |
| Semipermeable | Partially but not freely or wholly permeable specifically : permeable to some usually small molecules but not to other usually larger particles. |
| Phospholipid | A phospholipid is a type of lipid molecule that is the main component of the cell membrane. ... Each phospholipid is made up of two fatty acids, a phosphate group, and a glycerol molecule. When many phospholipids line up, they form a double layer that is characteristic of all cell membranes. |
