| Term | Definition |
|---|---|
| plasma membrane | protects the cell |
| nucleoid | contains and controls genetic material in prokaryotic cell |
| nucleus | contains most of cell's genes |
| nuclear envelope | encloses nucleus, has nuclear pores |
| nuclear pore | regulates movement of substances in and out of nucleus |
| chromatin | DNA and proteins condense to form chromosomes as cell prepares to divide |
| nucleolus | makes ribosomal RNA |
| ribosomes | carries out protein synthesis in... -cytosol (free, does not exit cell) -outside of ER or NE (bound, exits cell) |
| smooth ER | -synthesizes lipids -metabolizes carbs -detoxifies drugs+poisons -stores calcium ions |
| rough ER | -ribosomes secrete glycoproteins -distributes transport vesicles -makes membrane for cell |
| transport vesicle | transports parts of endomembrane system |
| golgi apparatus | -modifies products of ER -manufactures certain macromolecules -receives+modifies protein |
| lysosomes | enzymes digest macromolecules |
| large central vacuole | stores water in plant cell |
| mitochondria | site of cellular respiration |
| chloroplasts | site of photosynthesis |
| cytoskeleton | organizes cell's structures+activities |
