How does a membrane of cell differ frm the nuclear membrame?
Answers
They differ in many different ways, in terms of function, structure, types of proteins in the membrane, etc. I’ll just describe the most basic structural difference.
The cell membrane is a lipid bilayer that encloses the entire cell, with or without infolding (invaginations). It is a continuous sheet without interruption (not counting pores created by proteins)
The nuclear membrane is not a continuous sheet. It is made up of a series of flattened vesicles, fitted together side by side like a jigsaw puzzle. There are often large holes and gaps in and between these segments, to allow for efficient movement of materials to and from the material inside the nucleus. Each of these vesicles has a continuous lipid bilayer membrane similar to the cell membrane. When flattened, of course, this means the nuclear “membrane” will actually have four lipid layers
