The nuclear envelope is a derivative of:
Correct answer: B. Rough endoplasmic reticulum
- A. Microtubules
- B. Rough endoplasmic reticulum
- C. Smooth endoplasmic reticulum
- D. Membrane of Golgi complex
Explanation
The rough endoplasmic reticulum (RER) is directly involved in the formation of the nuclear envelope. During cell division, the nuclear envelope disintegrates, and its components are absorbed into the RER. After division, the RER helps in reassembling the nuclear envelope, making it a derivative of the RER.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
