Which one of the following is a single membrane enclosed organelle?
Correct answer: B. Lysosome
- A. Mitochondria
- B. Lysosome
- C. Nucleus
- D. Chloroplast
Explanation
The correct answer is Lysosome, as it is the only organelle among the options that is enclosed by a single membrane. This membrane encloses enzymes crucial for breaking down cellular components and waste. In contrast, Mitochondria, the Nucleus, and Chloroplasts all have double membranes. Mitochondria have a double membrane with an inner folded structure for ATP production, the Nucleus is enclosed by the nuclear envelope consisting of two lipid bilayers, and Chloroplasts have double outer membranes supporting the photosynthetic machinery within.
