Answer:
A: nuclear membrane, endoplasmic reticulum, Golgi apparatus, and vesicle
This structure distinguishes a eukaryotic cell from a prokaryotic cell which are a part of the internal membrane system
Explanation:
"Eukaryotic cells" are more compound than "prokaryotic cells". Plasma membrane in eukaryotic cells separates the "internal contents" of the cell from outside.
Internal membrane (Or endomembrane) system is a group of membranes and organelles that work together and help to assemble and transfer lipids and proteins to the body. This includes nuclear membrane, endoplasmic reticulum, Golgi apparatus, and vesicle. These are not found in prokaryotic cells. Plasma membrane is inside the Internal membrane system.
