Cell Organelles AP
| Term | Definition |
|---|---|
| Nucleus | The control centre, it holds the DNA. |
| Nucleolus | Within the nucleus and makes ribosomes. |
| Ribosomes | make proteins and is found in all cells. |
| Endoplasmic Reticulum (ER) | The roads; internal delivery system of the cell |
| Rough ER | rough in appearance because it has ribosomes and transports proteins. (which are made from ribosomes) |
| Smooth ER | transports fats and lipids- ribosome free. |
| Golgi complex | the shippers -packages, modifies, and transports material to different location inside/outside of the cell. |
| Lysosomes (bigger than ribosomes) | known as"suicide sacks" they break down food into particles that the rest of the cell can use. Also destroy old cells and pathogens. |
| cell membrane | controls what passes in and out of the cell through its pores. The size of the pore determines the size of the molecule that can pass through the membrane. |
| centrosomes | a clear area of cytoplasm containing centrioles. |
| Centrioles | aids in cell division and form a spindle of threads that guide the chromosomes. |
| mitochondria | the power house- makes energy by breaking down food to make ATP. |
| ATP | the major fuel for all cell activity that require energy. |
| water and carbon dioxide are a by product of | cellular respiration. |
| organelles | small organs |
| DNA | strings of chromosomes |
| tissues | big groups of cells form these |
| cellular respiration | cells use oxygen to break down the sugar glucose and store its energy in molecules of ATP. |
| chromosomes | carry all the information needed to make an entire human being |
