BL200Cell organelles
Learn the cell organelles for Level 2 Biology
| Question | Answer |
|---|---|
| golgi apparatus | multi-layered organelle near the nucleus used for packaging of materials to be transported out of the cell |
| Cell wall | multi-layered, sturdy structure composed of cellulose that provides plants and other organisms with their rigidity |
| Centrioles | essential tubular organelles found near the nucleus in pairs that aid in cellular division |
| Chloroplasts | collective term for cytosol and all the organelles contained in it (outside the nucleus and within the plasma membrane) |
| Cytoplasm | collective term for cytosol and all the organelles contained in it (outside the nucleus and within the plasma membrane) |
| Cytoskeleton | network of microtubules that support and give structure to cell while aiding in intracellular transport |
| Cytosol | jelly-like material that contains the organelles between the nucleus and the plasma membrane |
| Endoplasmic reticulum | the cell's highway transport system composed of tubes and membranes connected to the nuclear membrane and extending through the cytoplasm that is also utilized for storing and separating |
| Flagellum | an extension on many unicellular organisms that enables movement through whip-like motions |
| Lysosomes | the digestive plants of food for the cell, changes shape from task to task |
| Mitochondria | genetically independent organelles that produce energy for the cells along their many internal folds, called cristae |
| Nuclear membrane | membrane surrounding the nucleus that is covered with pores and controls nuclear traffic |
| Nucleolus | spherical structure within the nucleus that contains RNA |
| Nucleus | spherical organelle that is the cell's control center |
| Plasma membrane | outer membrane of cells composed of proteins and a phospholipid bi-layer that controls cellular traffic |
| Ribosomes | extremely small grain-like organelle that provides the sites for protein synthesis (they may be free in the cytoplasm or attached to the endoplasmic reticulum) |
| Vacuoles | membrane-bound organelles in the cytoplasm that are used for storage and digestion |
