Detailed explanation-1: -The nuclear envelope has a complex structure, consisting of two nuclear membranes, an underlying nuclear lamina, and nuclear pore complexes (Figure 8.1). The nucleus is surrounded by a system of two concentric membranes, called the inner and outer nuclear membranes.

Detailed explanation-2: -The nucleus is bounded by a double membrane, called the nuclear envelope. Within the double membrane nuclear envelope are passages which large molceules can pass through called nuclear pores. Each Nucleus contains one or more nucleolus; the site of ribosome synthesis.

Detailed explanation-3: -The nuclear envelope, also known as the nuclear membrane, is made up of two lipid bilayer membranes that in eukaryotic cells surround the nucleus, which encloses the genetic material.

Detailed explanation-4: -Nuclear Envelope, Transport The NE consists of two continuous, distinct parallel membranes, the inner and outer nuclear membranes, enclosing a perinuclear space (Figure 1). The outer nuclear membrane and perinuclear space are continuous with the endoplasmic reticulum, and share its functions.

Detailed explanation-5: -The nuclear envelope is also called nuclear membrane, is a double membrane layer that separates the contents of the nucleus from the rest of the cell. It is a barrier that physically protects the cells DNA from the chemical reactions that are occurring elsewhere in the cell.
