Practice Question

Which organelle makes ribosomes?

Answer Choices:

Correct Answer:

nucleolus

Rationale:

🔺 The nucleolus is the organelle inside the nucleus where ribosome subunits are produced.

🔺 It synthesizes and assembles ribosomal RNA (rRNA) with proteins imported from the cytoplasm.

🔺 These subunits later combine in the cytoplasm to form functional ribosomes.

🔺 Ribosomes are essential for protein synthesis, so the nucleolus indirectly supports all cell growth and repair processes.

🔺 Without a nucleolus, cells would not be able to produce ribosomes efficiently, impairing protein production.
