Rough endoplasmic reticulum is distinguished from smooth endoplasmic reticulum by the presence of
Correct answer: B. ribosomes on its surface
- A. cristae
- B. ribosomes on its surface
- C. thylakoids
- D. a double nuclear envelope
Explanation
Ribosomes bound to the outer face of the membrane give rough ER its appearance and its function, which is synthesising proteins destined for secretion or for membranes. Smooth ER has no ribosomes and handles lipid and steroid synthesis and detoxification, which is why liver cells are rich in it. Cristae belong to mitochondria and thylakoids to chloroplasts.

About Cytoplasmic Organelles
Cytoplasmic organelles are the specialized structures suspended in cytoplasm, including mitochondria, ribosomes, endoplasmic reticulum, Golgi apparatus, lysosomes, vacuoles and centrosomes. Questions compare their structures and functions in animal and plant cells, including chloroplasts and the role of the endomembrane system in transport and secretion.
