NEET BIOLOGY

Detailed explanation-1: -The nuclear membrane is a double layer that encloses the cell’s nucleus, where the chromosomes reside.

Detailed explanation-2: -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-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: -In eukaryotic cells, the nucleus is separated from the cytoplasm and surrounded by a nuclear envelope. This envelope safeguards the DNA contained in the nucleus.

Detailed explanation-5: -1. Plant and animal cells are eukaryotic, meaning that they have nuclei. Eukaryotic cells are found in plants, animals, fungi, and protists. They generally have a nucleus-an organelle surrounded by a membrane called the nuclear envelope-where DNA is stored.
