Question

which organelle makes the proteins that are needed by the cell?
cell membrane
golgi apparatus
ribosomes
nucleus

Explanation:

To determine the organelle that makes proteins, we analyze each option:

• Cell membrane: Regulates substance entry/exit, not protein synthesis.
• Golgi apparatus: Modifies, sorts, and packages proteins, not synthesizes them.
• Ribosomes: Are the sites of protein synthesis, translating genetic information into proteins.
• Nucleus: Contains genetic material and controls cell activities, but does not directly synthesize proteins.

Answer:

C. ribosomes
