The role of the nucleus in cellular activities

Introduction:

The nucleus controls different cellular metabolic activities as well as hereditary activities of the eukaryotic cells. Nucleus serves as the main unique feature of eukaryotic cells, hence eukaryotic cells are called true nucleuses cells. But some lower organisms like bacteria are not like that therefore bacteria cells are called perikaryon or nucleoid cells or prokaryotic cells.

Most of the cells have only one nucleus that is uninucleate or monokaryotic cells, however, some animals have two nuclei in single cells it’s called binucleate for example Paramecium caudatum. Some animals have three nuclei in single cell they called as trinucleate cells for example, Paramecium Aurelia same like some animal cells has many nucleus it is called multinucleate cells example plasmodium in slime moulds. It is syncytium in animal cells and coenocytic in plant cells, a nucleus is absent in some mature cells like mammalian RBCs (red blood cells) and sieve tube cells. They are called nucleated cells. The term enucleate is used more commonly for cells from which nucleus has been removed.
