| Question | Answer |
|---|---|
| nucleus | contains DNA |
| nucleoplasm | gel-like matrix inside the nucleus |
| nucleolus | where ribosomes are made |
| chromatin | made of DNA and protein |
| nuclear envelope | surrounds the nucleus, is a double phospholipid bi-layer |
| cytoplasm | gel-like matrix located outside the nucleus |
| rough endoplasmic reticulum | site of protein synthesis, covered in ribosomes |
| smooth endoplasmic reticulum | synthesizes lipids and detoxifies poisons and drugs |
| golgi apparatus | where proteins are modified into final proteins and repackaged into secretory vesicles |
| lysosomes | digest old organelles |
| peroxisomes | neutralization of toxins, break down of fatty acids, conversion of hydrogen peroxide into oxygen and water. |
| mitochondria | synthesizing of energy |
| free ribosomes | synthesize proteins for metabolic process |
| cytoskeleton | internal framework of the cell |
| centriole | produce micro tubules of cytoskeleton, and micro tubule spindle in mitosis and meiosis. |
