NEET BIOLOGY

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: -Nuclear Membrane The nuclear membrane is a double layer that encloses the cell’s nucleus, where the chromosomes reside. The nuclear membrane serves to separate the chromosomes from the cell’s cytoplasm and other contents.

Detailed explanation-3: -It is surrounded by the nuclear envelope, a double nuclear membrane (outer and inner), which separates the nucleus from the cytoplasm. The outer membrane is continuous with the rough endoplasmic reticulum. The nuclear envelope contains pores which control the movement of substances in and out of the nucleus.
