Primordial germ cells are diploid (2n) and in the process of meiosis cell division, they create female and male gamete cells. In meiosis cell division, the nucleus is divided twice but the chromosomes are divided only once. As a result, the daughter cells get half of the number of chromosomes of the mother cell.

Eukaryotic cells contain a well-developed nucleus, which means nuclear materials are well arranged and surrounded by a nuclear membrane. Chromosomes in this cell contain DNA, protein, histone, and other components. The cells of a multicellular organism have these features and this is why they are named as eukaryotic cells.
Cells that contain a well-developed nucleus, which means nuclear materials are well arranged and surrounded by a nuclear membrane, are known as eukaryotic cells. Eukaryotic cells are of two types somatic cell and germ cell. Ribosomes and other organelles are present in this cell. Most of the animal cells are eukaryotic.
Organs are the special parts of animals composed of one or several kinds of tissue and are capable of performing particular functions.
Intercalated discs are disc-like parts of the principal axis of axon.
Axollema is the plasma membrane of the principal axis of axon.
If two or more organs act together to perform similar physiological functions of the body, then the organs are named system.
Cytoplasm is a clear, jelly-like fluid that fills the inside of the cell and surrounds all the internal structures.
