Question

State the difference between Nucleus and nucleolus.

Answer 1

Hint: They are present inside the cell, one of them is organelle while the other is sub-organelle because it is located inside the organelle. These two are the characteristic feature of the eukaryotic cell.

Complete step-by-step answer:
Every organism has the most basic component of life, which is the cell, and in almost all cells there is the nucleus.
Difference between nucleus and nucleolus

Nucleus	Nucleolus
It is a large spherical shaped structure present in the cell	It is very small and is present inside the nucleus.
It is bounded by double-layered nuclear membranes.	It does not consist of any nuclear membrane.
It is the main cell organelle.	It is a sub-organelle of the nucleus.
It contains chromosomes.	It does not contain any chromosomes.
It is the brain of the cell because it controls all the activities of the cell.	It is simply a part of the nucleus.
It is rich in DNA, the genetic material.	It is rich in RNA.
Its function is to control cellular functions as well as inheritance.	Its main function is the arrangement of ribosomes and is involved in RNA metabolism.
It has cellular membranes.	It has fibrillar centers, dense fibrillar centers, and the granular component.

Note: The nucleolus is responsible for the collection and transcription of RNA, particularly the ribosomal nucleic acid or rRNA. It is also responsible for the synthesis of the ribosome which is essential to perform activities in the entire cell.
