Cell Organelles
An introduction to cell organelles
| Term | Definition |
|---|---|
| Nuclear envelope | A double membrane surrounding the nucleus |
| Nuclear pore | A gateway to allow materials to move between the cytoplasm and the nucleus |
| Nucleolus | Region where ribosomes are assembled |
| Rough ER | Series of flattened membrane stacks studded with ribosomes where secretory proteins are made |
| Smooth ER | Network of membranes where lipid synthesis and detoxification reactions occur |
| Golgi | Series of membrane sacks where proteins are modified and sorted to their correct destinations |
| Mitochondria | Double membrane structures that produce the ATP used by the cell as an energy source |
| Microvilli | Highly folded region of the cell surface membrane to allow easier faster movement of materials into and out of the cell |
| Centrioles | Organise the microtubules within the cell and involved in cell division |
| Microtubules | Protein scaffold within the cell involved in directing and organising materials within the cytoplasm |
| Ribosomes | produce proteins within the cell. Maybe free within the cytoplasm or located on the rough ER |
| Cell surface membrane | Regulates the movement of materials into and out of the cell |
