Question

How are the nucleus and the nucleolus different?

Answer 1

Hint: As we know that nucleus and the nucleolus are present inside the cell. Out of these two one is organelle while the other one is sub organelle because it is basically located inside the cell. We can say that these are the two main features of eukaryotic cells.

Complete answer:
Let us discuss the difference in between nucleus and the nucleolus.

Nucleus	Nucleolus
1. As we know that nucleus is a large spherical shaped structure present in the cell.	1. As we know that nucleolus is small in structure and is present in the cell.
2. nucleus is the main cell organelle	2. nucleolus is the sub organelle of the cell
3. it consist of double layered nuclear membrane	3. it does not consist of any nuclear membrane
4. it is found that nucleus have chromosomes	4. it is found that nucleolus doesn’t have chromosomes
5. nucleus is rich in DNA	5. nucleolus is rich in RNA
6. The nucleus is basically called the brain of the cell, as it controls all the major activities of the cell.	6. nucleolus is simply a part of the nucleus.
7. nucleus is found to have cellular membranes	7. nucleolus is found to have fibrillary centres, granular component and dense fibrillar centres

Note:
- As we know that nucleolus is responsible for the transcription and collection of the RNA, mainly the rRNA, that is ribosomal nucleic acid. It is also found that it is also responsible for the synthesis of the ribosome, that is essential for performing the activities in the cell
