Plant Cell Diagram Nuclear Envelope. Diagram of plant cell wall. The nuclear envelope’s surface area extends and doubles the nuclear pores during the interphase part of cell division.

The space between the layers is called the perinuclear space and appears to connect with the rough endoplasmic reticulum. Nuclear membrane shields the nucleus with a double membrane by many pores that help in controlling the crossing of macromolecules such as proteins and rna and permit free passage of water, ions, atp and small molecules.
