Difference between Nucleolus and Nucleus
Difference between Nucleolus and Nucleus are in tabular form below –
No. | Nucleolus |
Nucleus |
1. | A part which is non-membrane bound structure and made up of nucleic acids and proteins, and mainly present within nucleus, this is referred as nucleolus. | A part that contains the cell’s hereditary information and a membrane bound structure which controls reproduction and growth, this is referred as Nucleus. |
2. | This structure is a non-membrane bound structure. | This structure is a membrane bound structure. |
3. | Nucleolus does not contain nuclear membrane and chromosomes. | Nucleus contains nuclear membrane and chromosomes. |
4. | This is rich in RNA and not in DNA. | This is not rich in RNA and not in RNA. |
5. | Nucleolus mainly contains fibrillar center, nuclear vacuole, granular component and dense fibrillar component. | Composition of nucleus mainly includes nucleolus, lamina nucleoplasm, chromosomes, pores, nuclear envelope and other subnuclear bodies. |
6. | It is a part of nucleus. | It is a cell organelle. |
7. | Production of rRNA is the main function of nucleolus. | Production of DNA and housing for the genetic material both are the main functions of nucleus. |
