Which of the following is a double membrane-bound organelle containing pores?
Correct answer: D. Nucleus
- A. Chloroplast
- B. Mitochondria
- C. Endoplasmic reticulum
- D. Nucleus
Explanation
The nucleus is a double membrane-bound organelle. The membrane of the nucleus is called the nuclear envelope and is composed of an inner membrane and an outer membrane. At certain points, these two are continuous with each other, resulting in the formation of pores called nuclear pores. The nuclear pores are selective and allow the transport of materials between the nucleus and the cytoplasm.
