nucleus is an organelle found in eukaryotic cells. it is spherical shaped . inside its fully closed nuclear membrane , it contains the majority of cell's genetic material. the material is organised as DNA molecules, along with variety of proteins, to form chromosomes.
its function is that it stores cell's hereditary material or DNA and it coordinates the cell's activities

Nucleus is the largest cell organelle. It regulates and coordinates various life processes of the cell. It plays an important part in cell division. It contains factors which determine heredity.
Nucleus is a small spherical mass located somewhat in the centre of the cytoplasm. It has a delicate nuclear membrane which is filled with a relatively dense nucleoplasm. In the nucleoplasm there are certain thread like structures called chromatin fibres. During cell division the chromatin fibres become thick and ribbon like. These fibres are then called chromosomes. Each nucleus also has, at least, one nucleolus in it. Some cells may have more than one nucleolus. The number of nucleoli in a cell is fixed. The nucleolus participates in protein synthesis.
The chromosomes carry the genetic characters from the parent to the offspring through the union of the egg of the female and the sperm of the male.
