| Term | Definition |
|---|---|
| Phospholipid Bilayer | two-layer "sandwich" of molecules that surrounds a cell |
| Facilitated Diffusion | pathway provided by transport proteins that helps certain molecules pass through a membrane |
| Endocytosis | process of taking material into a cell within vesicles that bud inward from the plasma membrane |
| Pinocytosis | A process of taking in fluid together with its contents into the cell by forming narrow channels through its membrane that pinch off into vesicles, and fuse with lysosomes that hydrolyze or break down contents. |
| Hypertonic Solution | A solution that has higher osmotic pressure (or has more solutes) than another solution to which it is compared. |
| Photosynthesis | process by which plants use the sun's energy to convert water and carbon dioxide into sugars |
| ATP | (adenosine triphosphate) main energy source that cells use for most of their work |
| Transport Protein | A transport protein is a protein which serves the function of moving other materials within an organism. Transport proteins are vital to the growth and life of all living things. There are several different kinds of transport proteins |
| Active Transport | movement of molecules across a membrane requiring energy to be expended by the cell |
| Exocytosis | process of exporting proteins from a cell by a vesicle fusing with the plasma membrane and spilling the proteins outside the cell |
| Isotonic Solution | having a solute concentration equal to that of another solution |
| Sodium-Potassium Pump | s an antiporter enzyme located in the plasma membrane of all animal cells |
| Cellular Respiration | chemical process that uses oxygen to convert chemical energy stored in organic molecules into ATP |
| Aerobic | elating to, involving, or requiring free oxygen |
| Osmosis | passive transport of water across a selectively permeable membrane |
| Passive Transport | diffusion across a membrane requiring only the random motion of molecules with no energy expended by the cell |
| Phagocytosis | the ingestion of bacteria or other material by phagocytes and ameboid protozoans. |
| Hypotonic Solution | having a lower concentration of solute than another solution |
| Fermentation | cellular process of making ATP without oxygen |
| Chlorophyll | pigment that gives a chloroplast its green color; uses light energy to split water molecules during photosynthesis |
| Anaerobic | without oxygen |
