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 |
