Which organelle is covered with ribosomes?

Golgi apparatus
Mitochondria
Rough endoplasmic reticulum
Smooth endoplasmic reticulum

The correct answer is: Rough endoplasmic reticulum

The rough endoplasmic reticulum (Rough ER) is covered with ribosomes, making it appear bumpy or "rough" under a microscope. This is because ribosomes are responsible for protein synthesis, and the Rough ER is a site for protein production and modification. The Golgi apparatus (A) is responsible for sorting and packaging proteins, but does not contain ribosomes. Mitochondria (B) are the energy powerhouse of the cell and do not have ribosomes attached. The smooth endoplasmic reticulum (D) is involved in lipid synthesis and detoxification, and does not contain ribosomes. Therefore, the correct answer is C.
