Question

what is the main function of the nucleolus?
a the production of cytoplasm
b the production of lipids
c the production of proteins
d the production of ribosomes

Explanation:

The nucleolus is a structure within the nucleus of a cell. Its main role is in the production of ribosomes. Ribosomes are essential for protein synthesis in the cell. Cytoplasm is the jelly - like substance within the cell (not produced by the nucleolus). Lipids are mainly produced in the endoplasmic reticulum. Proteins are synthesized by ribosomes (which are produced by the nucleolus, but the direct production of proteins is not the nucleolus's main function).

Answer:

d. The production of ribosomes
