Organelles
Science unit 1 test, all the components of a cell
| Question | Answer |
|---|---|
| Organelles | Parts of cell |
| Nucleus | Keeps the DNA of a cell |
| Cytoplasm | Holds all the organelles in place and allows chemical reactions to happen |
| Cytoskeleton | |
| Ribosomes | They make protein *DNA codes for, protein* there are two types: - some can be free in cytoplasm and some can be attached to another organelle* |
| Nucleolus | Inside a Nucleus produces ribosome |
| Endoplasmic Reticulum(ER) | Transporting molecules around Molicules that leave ER can be sent away on vesicles |
| Two types of ER | - rough ER = ribosomes are attached to it(protein producing and transporting) - smooth ER = doesnt have a ribosomes attached.(detochcification, can make some type of lipids(fats) |
| Golgi Apparatus | Packages and ships proteins. |
| Mitochondria | Collects the glucose and oxygen to make energy in form of ATP |
| Chloroplast(Plants) | Uses light energy to make glucose using photosynthesis |
| Vacuoles | Storage for materials Plants: Central Vacoule Animals: Smaller and several |
| Cell wall(plants) | Additional protection and shape maintenance |
| Centriole(animals) | |
| Lysosomes(animals) | |
| Cell membrane | Controls what goes in |
