What is the function of the nucleolus?

Explanation:
The nucleolus is the ribosome factory of the cell. It transcribes ribosomal RNA and assembles ribosomal subunits by combining rRNA with ribosomal proteins, then ships these subunits out to the cytoplasm where they form functional ribosomes for protein synthesis. That’s why its function is to manufacture ribosomes. Other cellular activities mentioned occur in different organelles: lipids are made in the smooth endoplasmic reticulum, digestion happens in lysosomes, and energy is released in mitochondria.
