Ruff. Organelles
Organelle Study Stack
| Term | Definition |
|---|---|
| Cells | The basic unit of structure and function in all living organisms |
| Organelles | Known as "little organs." They are small structures inside the cell that carry out specific functions |
| Nucleus | Holds the cell's DNA. It is the information center of the cell and controls all of the cell's activities. |
| Mitochondria | Provides energy for the cell by releasing energy that was stored in food. "Powerhouse" |
| Nucleolus | Found inside of the nucleus and is responsible for making ribosomes |
| Ribosomes | The site where proteins are made |
| Golgi Body (Golgi Apparatus) | The cell's "post office". It receives proteins and packages them and distributes them to other parts of the cell |
| Cell Membrane | The "gatekeeper" of the cell. It regulates what can enter and leave the cell. It also provides protection and support |
| Lysosome | Small structures that contain digestive enzymes that break down materials and waste in the cell. Known as the recycling center of the cell. |
| Vacuole | Storage center of the cell. Mostly stores water and carbohydrates. Very large in plant cells. |
| Cytoplasm | Gel-like substance that holds all of the organelles. it is found between the nucleus and the cell membrane. |
| Cell Wall | Only found in plant cells. It is a thick, rigid structure found surrounding the outside of the plant cell. It provides protection and support. It gives the plant cell it's rectangular shape |
| Chloroplasts | Green Structure that captures energy from the sun during photosynthesis to make food for the cell. Only found in plant cells |
| Endoplasmic Reticulum (ER) | Transports and assembles proteins in the cell. The "highway" |
