Detailed explanation-1: -The nucleus is surrounded by a system of two concentric membranes, called the inner and outer nuclear membranes. The outer nuclear membrane is continuous with the endoplasmic reticulum, so the space between the inner and outer nuclear membranes is directly connected with the lumen of the endoplasmic reticulum.
Detailed explanation-2: -The nuclear membrane encloses the DNA within the nucleus and protects it from the substances in the cytoplasm. It also regulates the entry and exit of substances in the nucleus.
Detailed explanation-3: -The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.
