Question

1. name three cell organelles.
2. what organelle is in the center of the cell and contains dna?
3. there are two endoplasmic reticulum. what are their names?
4. which organelles make protein?
5. what else does the er produce?

Explanation:

1. Cell organelles are specialized structures in cells with specific functions; three common ones are selected.
2. This organelle acts as the cell's control center holding genetic material.
3. The two types of ER are distinguished by their structure and function.
4. These organelles are responsible for protein synthesis in cells.
5. The endoplasmic reticulum (ER) has lipid production as a key secondary function.

Answer:

1. Mitochondrion, ribosome, Golgi apparatus
2. Nucleus
3. Rough endoplasmic reticulum (Rough ER), Smooth endoplasmic reticulum (Smooth ER)
4. Ribosomes (and rough endoplasmic reticulum, as it has embedded ribosomes for protein synthesis)
5. Lipids (including phospholipids and steroids)
