| Question | Answer |
| Cell Membrane | The semipermeable membrane surrounding the cytoplasm of a cell |
| Cell Wall | Structure that surrounds a plant, protistan, fungal, or bacterial cell and maintains the cell's shape and rigidity |
| Cellular Respiration | Metabolic reactions that use the energy primarily from carbohydrate but also fatty acid or amino |
| Chloroplast | Membranous organelle that contains chlorophyll and is the site of photosynthesis |
| Chromatin | Network of fibrils consisting of DNA and associated proteins observed within a nucleus that is not dividing |
| Chromosome | Rodlike structure in then nucleus seen during cell division; contains the hereditary units, or genes |
| Cristae | Short, fingerlike projections formed by the folding of the inner membrane of mitochondria |
| Cytoplasm | Contents of a cell between the nucleus and the plasma membrane that contains the organelles |
| Cytoskeleton | Internal framework of a cell, consisting of microtubules, actin filaments, and intermediate filaments |
| Golgi Body | Organelle, consisting of flattened saccules and also vessels, that processes, packages, and distributes molecules about of front he cell |
| Lysosomes | Membrane- bounded vesicle that contains hydrolytic enzymes for digesting macromolecules |
| Matrix | Unstructured semifluid substance that fills the space between cells in connective tissues or inside organelles |
| Mitochondria | Membrane-bounded organelle in which ATP molecules are produced during the process of cellular respiration |
| Nuclear Envelope | DOuble membrane tjat surrounds the nucleus and is continuous with the endoplasmic reticulum |
| Nuclear Pore | Opening int eh nuclear envelope that permits the passage of proteins into the nucleus and ribosomes subunits out of the nucleus |
| Nucleolus | Dark-staning, spherical body in the nucleus that produces ribosomal subunits |
| Nucleus | Membrane-bounded organelle within a eukaryotic cell that contains chromosomes and controls the structure and function of the cell |
| Organelle | Small, often membranous structure in the cytoplasm, having a specific structure and function |
| Polysome | A cluster of ribosomes held together by a strand of messenger RNA |
| Ribosome | RNA and protein in two subunits; sire fo protein synthesis in the cytoplasm |
| Rough Endoplasmic Reticulum | |
