Question

the function of the nucleolus is to make _______.
a mitochondria
b endoplasmic reticulum
c chromosomes
d ribosomes

Explanation:

To solve this, we recall the function of the nucleolus. The nucleolus is a structure within the nucleus of a cell, and its primary function is related to the production of ribosomes. Let's analyze each option:

• Option A: Mitochondria are produced through a different process and not by the nucleolus.
• Option B: The endoplasmic reticulum has its own formation mechanisms and is not made by the nucleolus.
• Option C: Chromosomes are composed of DNA and proteins and are not synthesized by the nucleolus.
• Option D: The nucleolus is responsible for the assembly of ribosomal subunits, which are part of ribosomes. So the nucleolus makes ribosomes.

Answer:

D. ribosomes
