NEET BIOLOGY

Detailed explanation-1: -The nucleus is a membrane-enclosed organelle, found in most eukaryotic cells, which stores the genetic material (DNA). The nucleus is surrounded by a double lipid bilayer, the nuclear envelope, which is embedded with nuclear pores.

Detailed explanation-2: -These membrane-bound structures are called organelles. In eukaryotes, the cell’s genetic material, or DNA, is contained within an organelle called the nucleus, where it is organized in long molecules called chromosomes.

Detailed explanation-3: -The nucleus is a membrane-bound structure that contains the cell’s hereditary information and controls the cell’s growth and reproduction. It is the most prominent organelle in the cell. It is surrounded by a structure called the nuclear envelope. This membrane separates the contents of the nucleus from the cytoplasm.

Detailed explanation-4: -These essential organelles can be found in the cytoplasm of a cell or bound to the membrane of the endoplasmic reticulum.
