Structure of Nucleus
Chemically they are composed of nucleic acid, RNA, and protein. Physically, they are composed of the following components:
- Nuclear membrane: The nuclear membrane is the double-layered transparent membrane that forms the nucleus's outer covering. The outer membrane is permeable, but the inner membrane is not.
- Nucleoplasm: It is a clear and dense fluid surrounded by a nuclear membrane. It contains a nucleolus and chromosomes.
- Nucleolus: The nucleolus is the denser, smaller, rounder body found in the nucleus.
- Chromosome: A chromosome contains several genes, and these genes are responsible for expressing the characteristics of various species.
Functions of the different parts of a Nucleus
- The primary function of the nuclear membrane is to keep the nucleoplasm, chromosomes, and nucleus separate from the cytoplasm. This membrane is also used to transport internal materials and cytoplasm.
- Nucleoplasm stores chromosomes and performs various organic functions.
- Nucleolus synthesizes and stores various types of RNA and protein.
- The chromosome contains and transmits the organism's hereditary properties.
