b answer.

Nucleus of a cell

The spherical round body present in the centre of the cell is called nucleus.

It is an important component of the living cell.

Nucleus is separated from the cytoplasm by a membrane called the nuclear membrane.

The nuclear membrane is porous and allows the movement of materials between the cytoplasm and nucleus.

The nucleus consists of a spherically shaped dense mass called nucleolus. Nucleus also contains thread-like structures called chromosomes. These carry genes and help in inheritance or transfer of characters from the parents to the offspring.
