AP Biology chapter 6
| Question | Answer |
|---|---|
| Nucleus | Genetic material. Double membrane envelope with pores. Protein synthesis. |
| Ribosomes | Make protein. In the cytosol. |
| Endoplasmic Reticulum (ER) | Network of membrane-bounded tubules and sacs. |
| Smooth ER | Has no ribosomes, synthesis of lipids, metabolism of carbohydrates, and detoxification of drugs. |
| Rough ER | Synthesis of secretory proteins; sorts Golgi products |
| Golgi Apparatus | ER products are modified, stored, and then shipped in vesicles. |
| Lysosomes | Digestion of macromolecules and damaged organelles for recycling. |
| Phagocytosis | Eat up a whole cell. |
| Autophagy | Recycle cell's own organic material. |
| Vacuoles | Food digestion, pump excess water. |
| Mitochondrion | Cellular Respiration |
| Chloroplast | Photosynthesis. |
| Peroxisomes | Produce hydrogen peroxide to help break things down. Metabolism of fatty acids. |
| Cytoskeleton | Support, cell motility, and biochemical regulation. |
| Microtubules | Thickest. Shape, support, transport, and chromosome separation. |
| Microfilaments | Thinnest. Motility, cell division, and shape. |
| Intermediate Filaments | Shape and nucleus anchorage. |
| Centrioles | Microtubules in a ring. Used in cell replication. |
| Cilia / Flagella | [Hairs] Move about. |
| Cell Wall | Protection, shape, and regulation. |
| Fibronectins | Bind to receptor proteins in plasma membrane called integrins. |
| Plasmodesmata | [In plants] Cell wall pores for water and solute passages. |
| Tight Junctions | Fusion of neighboring cells; prevents leakage. |
| Desmosomes | Strong sheets of cells. |
| Gap Junctions | Cytoplasmic channels; allows passage of materials between cells. |
