| Term | Definition |
| Cell Theory | Generalization that all living things are composed of cells, and that cells are the basic unit of structure and function in living things |
| Organelle | Part of a cell with a specific function |
| Plasma Membrane | Thin outer boundary of a cell that regulates the traffic of chemicals between the cell and its surroundings |
| Nucleus(1) | In an atom, the central core that contains protons and neutrons |
| Nucleus(2) | In a cell, the part that houses the cell's genetic material in the form of DNA |
| Cytoplasm | Region of a cell between the nucleus and the plasma membrane |
| Cell Wall | Strong wall outside a plant cell's plasma membrane that protects the cell and maintains its shape |
| Prokaryotic Cell | Cell lacking a nucleus and most other organelles |
| Eukaryotic Cell | Cell with a nucleus (surrounded by its own membrane) and other internal organelles |
| Nuclear Envelope | Double membrane that surrounds a cell nucleus |
| Nucleolus | Ball-like mass of fibers and granules in a cell nucleus |
| Endoplasmic Reticulum | Network of membranes within a cell's cytoplasm that produces a variety of molecules |
| Golgi Apparatus | Cellular organelle that modifies, stores, and routes cell products |
| Vacuole | Membrane-bound sac that buds from the endoplasmic reticulum or the Golgi apparatus |
| Lysosome | Membrane-bound sac containing digestive enzymes that can break down proteins, nucleic acids, and polysaccharides |
| Mitochondria | Cellular organelles where cellular respiration occurs |
| Chloroplast | Organelle found in some plant cells and certain unicellular organisms where photosynthesis takes place |
| Ribosome | Cluster of proteins and nucleic acids that constructs proteins in a cell |
| Flagella | Long, thin, whip-like structures, with a core of microtubules, that enable some cells to move |
| Cilia | Short structures projecting from a cell and containing bundles of microtubules that move a cell through its surroundings or move fluid over the cell's surface |
| Cell Specialization | The characteristic of having separate roles for each type of cell in a multicellular organism; the cells are specifically designed for a certain function; it has a certain purpose or job |
| Centriole | A minute cylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division |
| Cytoskeleton | A microscopic network of protein filaments and tubules in the cytoplasm of many living cells, giving them shape and coherence |
| 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 | the ingestion of liquid into a cell by the Budding of small vesicles from the cell membrane. |
| Hypertonic Solution | Having a lower concentration of solute than another solution |
| 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 |
| 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 | Having a solute concentration equal to that of another solution |
| Sodium-Potassium Pump | A mechanism of active transport that moves potassium ions into and sodium ions out of a cell. |
| Cellular Respiration | Chemical process that uses oxygen to convert chemical energy stored in organic molecules into ATP |
| Aerobic | Requiring 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 and other material |
| 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 |
