What are the differences between nuclear membrane and nuclear envelope?

Posted February 10, 2023


The nuclear membrane and nuclear envelope are two distinct structural components that make up the nucleus. There are a few significant differences between the nuclear membrane and nuclear envelope. 

Nuclear membrane

The nuclear membrane is a lipid bilayer that forms a selective barrier for the transport of materials between the nucleoplasm and cytoplasm. The outer surface of the nuclear membrane is continuous with the endoplasmic reticulum

Nuclear envelope

Nuclear envelope is a structure made up of two nuclear membranes with nuclear pores. It completely envelopes the nucleus, separating the content of the nucleus from the cytoplasm.
