• It is one of the most important cell organelles.

• As the brain controls all the activities of our body, similarly the cell has nucleus that controls all activities of the cell.

More about nucleus!

• Nucleus is dense spherical like structure present in the cell.

• It is two membrane bounded cell organelles.

• Nucleus is made up of some parts. They are:–

◆ Nuclear membrane : Nucleus is surrounded by porous membrane called nuclear membrane.

◆ Nucleoplasm : Fluid present in the nucleus is called nucleoplasm.

◆ Nucleolus : This is the small spherical body present in the nucleus. It is made up of nucleo protien and RNA is found here.

◆ Chromosomes : Nucleoplasm has thread like structures called chromosomes. They contain genes that are responsible for the transfer of characteristics from one generation to anothee.

Answer 2

Nucleus

It is the nucleus which controls the whole cell. It a dynamic centre of the cell usually present in the middle. It has a membrane which is known as nuclear membrane which is porous and helps to transfer products from the nucleus to other parts. It contains chromatids which get converted into an entangled thread like structure and get thicker when the cell is about to reproduce. It is, then, will be known as chromosomes. Also, DNA (Deoxyribo Nucleic Acid) is found here. Genes are the functional segements of DNA which contain the necessary information from a generation to the other one.

Fact: A gram of DNA can contain approximately 215 petabytes of memory.
