| Actin | A ball-shaped protein used to make microfliaments |
| Active Transport | The movement of molecules across a membrane when the movement requires energy |
| Bilayer | Two layers |
| Cell Wall | The rigid layer of cellulose outside the plasma membrane of plant cells |
| Cellular Respiration | The process in which cells break down food to release energy |
| Central Vacuole | A large membrane sac in the center of a plant cell used for water storage |
| Chloroplast | An energy organelle in plants that harvest energy from the sun |
| Chlorophyll | A molecule in chloroplasts that traps energy from the sunlight |
| Chromosome | A structure in the nucleus made of individual DNA molecules folded and coiled together with proteins |
| Cilia | Small, hair-like structures made of microtubules; found on the outside of some cells to aid in movements |
| Cristae | The folded layers of the inner membrane inside mitochondria |
| Cytoplasm | The area inside a cell; contains organelles and cytosol |
| Cytoskeleton | A group of fibers running throughout the inside of a cell that supports the cell and helps the cell move |

| Endomembrane System | A group of organelles that help a cell make and use different molecules |
| Endoplasmic Reticulum | An organelle that makes different molecules |
| Exocytosis | A process in which a substance is released from a cell through a pouch that transports the substance to the cell surface |
| Extracellular Matrix | A sticky coating outside the plasma membrane of animal cells that joins cells together |
| Facilitated Diffusion | Passive transport that involves membrane proteins |
| Flagella | Long, tail-like structures made of microtubules; found on the outside of some cells to aid in movement |
