| Question | Answer |
|---|---|
| What is the function of the Nucleus? | Direct cells activities, information (DNA) Storage, and structural support |
| What are the components of the Nucleus? | Chromosomes, nucleolus, and nuclear lamina |
| Does the Nucleus have a membrane? | Double ("envelope") with openings called nuclear pores |
| What is the function of ribosomes? | assemble amino acids to form polypeptides, as well as protein synthesis |
| What are the components of Ribosomes? | RNA molecules, proteins |
| Do Ribosomes have membrane(s)? | none |
| What are contained in the Endomembrane System? | Rough ER, Smooth ER, Golgi apparatus, and Lysosomes |
