1. Biological function: The nucleus is called the brain of the cell. It controls all biological functions of cells.
2. Heredity: DNA molecules present in chromosomes control the heredity of organisms.
3. Protein synthesis: Nucleolus forms ribosomes and ribosomes make proteins.
4. Metabolism: Nucleus is the organelle that regulates cell metabolism.
5. Regulation of enzyme activity: Nucleoplasm serves as the main site of enzyme activity.
6. Variation and mutation: It causes variation and mutation in organisms. As a result, evolution takes place in the living world.
7. Metabolism: The nuclear membrane acts as a medium of exchange. It exchanges essential substances between cytoplasm and nucleoplasm.
8. Cell division: It plays an important role in cell division.
9. Differentiation: Nucleus controls cell differentiation during embryonic development.
10. Shape the cell: The nuclear membrane forms the various structural components of the cytoplasm. These elements help in cell shape.
