Yes-both plant and animal cells have a membrane-bound nucleus and organelles. The nuclear membrane controls the movement of molecules in and out of the nucleus.This is impo â¦ rtant for regulation and protection.onfidence votes 79. Nuclear membrane acts as a physical barrier, separating the nucleoplasm from the cytoplasm. It is a semipermeable membrane and allows transport of substances in and out of nucleus. Its inner membrane is involved in protein synthesis.
The nuclear membrane consists of two lipid bilayers âthe inner nuclear membrane, and the outer nuclear membrane. The space between the membranes is called the perinuclear space, a region contiguous with the lumen (inside) of the endoplasmic reticulum. It is usually about 20â40 nm wide.rom Wikipedia, the free encyclopedia. A nuclear membrane, also known as the nuclear envelope, nucleolemma or karyotheca, is the double lipid bilayer membrane which surrounds the genetic material and nucleolus in eukaryotic cells.
