Which organelle is double-membraned?
ARibosome with no membrane around it
BLysosome enclosed by a single membrane
CMitochondrion with outer and inner membranes
DCentrosome which is membrane-free in cytoplasm
Answer & Solution
Correct answer: C. Mitochondrion with outer and inner membranes
1. Single-membrane organelles include lysosomes, Golgi bodies and vacuoles.
2. Ribosomes and centrosomes lack any membrane.
3. The chapter section 2.7 says mitochondria are double-walled.
4. So the double-membraned organelle is the mitochondrion.
