- Stores heredity material in the form of deoxy-ribonucleic acid (DNA) strands.
The nucleus consists of the following main parts:
- Nucleolemma or nuclear membrane (karyotheca)
- Nuclear sap or karyolymph or nucleoplasm
- Chromatin network or fibres
- Nucleolus

Explanation:
The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus. The gel-like matrix in which the nuclear components are suspended is the nucleoplasm
control of the genetical information of the cell and thus the heredity characteristics of an organism,
control of the protein and enzyme synthesis
control of cell division and cell growth
storage of DNA, RNA and ribosome
regulation of the transcription of the mRNA to protein
production of ribosomes
