Nucleus || The Fundamental Unit of Life - 7 || for Class 9 in Hindi

In this Science (Biology) video in Hindi for class 9th we explained structure and function of cell nucleus. This is a topic from Chapter 5 - 'The fundamental unit of life' of science from NCERT.
Nucleus is bound by a membrane known as nuclear membrane. It has two phospholipid bilayer. Inside the nucleus, there is a fluid known as nucleoplasm. The nucleus contains DNA in the form of chromatin which is composed of DNA and histone protein. There is a very prominent region in the nucleus known as nucleolus and it creates r-RNA, which in turn creates ribosomes. The nuclear membrane has pores, known as nuclear pores, through which larger molecules, like proteins, can pass.
When DNA is enclosed in the envelope, viz., nuclear membrane, the cell is known as eukaryotic cell and when the envelope is absent and there is no prominent nuclear region, the cell is known as prokaryotic cell.

Back in 2017-18, I used to watch your physics lectures for my engineering entrance exam. Today, out of thin air came across this lectures. Being an engineer, biology subject is almost of no use to me. Despite I could not help leave the lecture in middle.
Still same same energy, same emphasis on concept and intuition building.
Good to listen to you after a long time. ❤
Love from Pakistan 🇵🇰

Biology istarha se sirf ek physics ki teacher hi padha sakta hai. Saare concept ekdm crystal clear ho rha hai.

[@dr.shakshigupta5879]

Nice video but what is difference between protoplasm and cytoplasm??

Cytoplasm is the living part of a cell inside the cell membrane but excludes the nucleus . Whereas the cytoplasm and nucleus together constitute the protoplasm

[@nixgaming4339]

i am watching it in class 8 xd

[@zmeuohyn]

Which one is correct?
1. Chromosome>gene>dna.
2. Chromosome>dna>gene.

[@vishugupta3610]

2nd i think

[@annidiaries2009]

1 because gens are found inside of chromosomes

[@SangeetaSagar-oc3qt]

Sir kis kis ma nucleus boundry nahi hoti

[@riddhirathor8700]

Hi

[@labanyahalder6907]

Chromosome kya hai

[@animator9556]

When chromatin undergoes condensation with non histone protein is known as chromosome
