Answer
Nucleus of a cell: Nucleus is an important component of the living cell. It is mostly spherical and located in the centre of the cell. It is separated from the cytoplasm by a membrane called the nuclear membrane. In addition, nucleus contains thread-like structures called chromosomes. These carry genes and help in inheritance or transfer of characters from the parents to the offspring. Nucleus, in addition to its role in inheritance, acts as control centre of the activities of the cell. The entire content of a living cell is known as protoplasm. It includes the cytoplasm and the nucleus. Protoplasm is called the living substance of the cell.
