Answer:
The correct answer is - they both have highly folded membranes.
Explanation:
Organelles such as the endoplasmic reticulum, Golgi apparatus, and mitochondria have highly folded double membranes. This highly folded membrane provides the increased surface area in the organelle.
As the inner membrane of these organelles is the site for many chemical reactions the highly folded or layered membranes get more space for such reactions to occur due to increased surface area.
Cell membrane separates cell from external environment whereas nuclear membrane separates nuclear environment form cell itself.
There is Nucleoplasm as a fluid under the nuclear envelope whereas cytoplasm under the cell membrane
