Cell Organelles
Cell organelles and their functions
| Question | Answer |
|---|---|
| nucleus | directs the cell’s activities |
| cell membrane | “gatekeeper” of the cell; controls what enters and leaves the cell |
| lysosome | contains chemicals that break down food and worn out cell parts |
| endoplasmic reticulum (ER) | transports proteins and other materials through the cell |
| mitochondrion | “powerhouse” of the cell; produces energy used by the cell from glucose |
| ribosomes | small structures where proteins are produced |
| vacuole | storage sac for water, nutrients, and waste |
| cell wall | a rigid layer of non-living material that surrounds the cell; provides protection and support |
| chloroplast | captures energy from the sun to produce food (glucose) |
| cytoplasm | gel-like material between the cell membrane and the nucleus; holds the organelles |
| nucleolus | organelle inside the nucleus where ribosomes are made |
| chromatin (chromosome) | contain the cell’s genetic material |
| Golgi body | receive materials from the ER and packages them for transport within or outside the cell |
| nuclear membrane | controls what enters and exits the cell’s nucleus |
