Mam your writing is very nice
Loved it bro❤
mam ko nazar na lage 😏😏
Right bro
@@sanataniOfficial359 mam ko thoda respect kar lo
Meri bdi bhn h he esi ❤
She said 987 times beta in whole video
Underrated Comment😂😂
Bhai focus dekh rahe ho padhai par nhi balki mam par😂😂
Padhle bc
Beta pad likh le
padh re jnj
Bhai padh le lekin aise mam ne 988 times beta bola hai
Mam awesome i loved the way u explained ♥️
now i think it's fairly said that students' interest in a particular subject is mostly dependent on teacher's way of teaching just fabulously amazing 😘
.. hello
Ha
True
What about aliens
Are they also made up of cells 😂
If living than yes , if not than no 🤣🤣🤣🤣🤣
cell nahi madam Beta...padha
It depends on the matter they are made of
Lime sicon aliens or aliens made of matter like dark matter can be different they may or may not have cells science can't say much about it
Because function of ER and Golgi body is nearly same to make modifications in protien and lipids by Golgi complex from taking ER.
Chal be
Mam your hand writing✍️ is very nice👏👍😊
Thanks for this video this helps a lot to understand concepts very clearly very nice explanation of topics thank you very much 🙏🙏
Thank you so much mam!☺☺ i have my finals next month and my whole syllabus is pending i was so worried about it because it's alot but you made it easier! The way of your teaching is just awesome.. I was able to understand everything!❤☺ thank you so much mam

Correct bro❤
Koi baat nhi glti ho jaati ha
Correct 💯
Ha Bhai sahi bol rhe ho but this is silly mistake, ye likhne me mistake ho jata hai aapse bhi kabhi hua hi hoga😢

Cell is the basic structural and functional unit of life
Mam in NCERT book is written Robert hooke is discovered cell in 1665
Thanks ma'am for your wonderful explanation 😊😊
Mam u r the best teacher in PW foundation and also my favourite one 😊😊
Same❤
Ll pw teacher are best
The Endoplasmic Reticulum and the Golgi Apparatus are closely located as the R.E.R synthesises Proteins which are in raw form, and thus, the Golgi Apparatus modifies, manufactures and packages the proteins for final use in the cell.
Thank you ma'am you've explained it very well. Firstly I thought that I would have to learn it word by word, but now I don't even have to memorise it, I understood it's process.
Cell is the basic structural functional unit of the life.cell is the discovered by Robert Hook in 1665.
He observed in slices of cork(part of bark of tree)
Dead cell is discovered by Robert hooks
Cork means a slice of old trees and it is a dead cell discovered by Robert Hooke.
😮

Thanks a lot mam aur itni dair khada rehnai kai liyai .hat's of to you.❤
Aap to ab 10th hogi na ? 😅
25:42 a single cell can't decide my life 😂😂😂😂😂

Mam in NCERT BOOK IS WRITTEN BASIC COMPONENTS OF CELL ARE NUCLEUS, CYTOPLASM, PLASMA MEMBRANE BUT YOU SAY CELL ORGANELLES, CYTOPLASM, PLASMA MEMBRANE PLZ MAM COMPLETE THIS DOUBT WHO IS RIGHT 😌
You are right 👍👍👍👍
Mam in class 8th the discovery of cell was made by an English scientist, Robert hooke in 1665 but mam you say he discover cell in 1655 please mam complete this doubt
Who is right
Please mam
@@Islamic__studies__09 both are same no?
Cell orgenelles mtlb bhi wohi hota ha cell components😊

Mam you had explained everything very briefly It is so good I hope you will be mine school teacher also
13:02 Robert Hooke discovered cell in1665 not in 1655
Right
Koi baat nhi yr book me hai na maam itna acha padha rahe hai wo dekheye na
Cell Is The Structural And Functional Unit Of All Living Organisms ✓✓

Thanks mam for this wonderful explanation..❤❤
It is important for my chs preparation 😊😊😊❤❤❤
Thanks mam
how to get the syllabus
Mam I have a question ❓
In prokaryotic cell ,
What is the space between the cell wall and the plasma membrane called ❓
Space between the cell wall and plasma membrane in a plasmolysed cell is filled with hypertonic solution
Thanks for this chapter mam , my exam has been starting from August 17/8/2022 and chapter is too much I.m.p mam aap ka concept ake dum clear hai mam 😘😘😘😍😍😍
Hi sexi. I love you 😙❣️
.
Mam in nucleus there is chromosome also which is thread like structure❤
yes yrr
Mam what we say the area between cell wall and plasma memberane in (PROKARYOTIC CELL)
Ma'am, the reason nucleus, endoplasmic reticulum and golgi apparatus live together is because when rough or smooth er produce lipids and proteins, the Golgi apparatus modifies the substances and transfers it to the nucleus
kinda true cuz' its the coding inscribed in the chromosomes and DNA for the functioning of a cell.....hope you learnt something kiddo.......
Thanks you too much mam and very very thanks you alakh sir for pw foundation for students future
Thanks man
As there is need of proteins and that is synthesis ia endoplasmic reticulum and when it goes to golgi apparatus is get modified thereafter it send to the place where it's need means in neucleus
Next week is my Viva and I was so worried and now my concept is clear .
Thank you so much Mam for this explanation😊
Thank you so much mam ❤
Golgi bodies , nucleus and endo plasmic reticulum remain near to each other as endo plasmic reticulum helps in the synthesis of proteins and lipids which get entered into the cell through plasma membrane. After they get synthesised , their modification takes place in Golgi bodies after which they are used by cell for further functions.

Hn to mam ne kya bola ?yhi to bola
Pel Diya galat Gyan, proteins and lipids are manufactured by RER and SER respectively.They don't come from outside of the cell but completely made by ER and Golgi Apparatus.
Initially discovered by Robert Hooke in 1665, the cell has a rich and interesting history that has ultimately given way to many of today's scientific advancements
Very informative... I am having fever but tomorrow is mh science test... This helped me alot ❤
ooh how much did u get?
@@kasmyt463 I couldn't give my science test 😭
🥲
Thank you for understanding me really really nicely explained and diagram is also so easy explain.🥰
Great lecture!!
The Great mam Your Hard Workind And Very Nice Writing ❤❤
Mam thank you for the wonderful explanation but at 31:34 you said that prokaryotes lack organelles.WHY SO??
Thank you so much mam 🤗😊
Tanks mam you are the best teacher in all CZcams▶️ 🌹🌹🌍🌽
thanks*
Thanks for the great explanation 😌
Which book is good for us to
make our basic strong
Your own standard books read them properly and make concept clear and also read extra points on google🎉
@PW-Foundation
There are three postulates of the cell theory whu u have mentioned only two
Your way of explanation is too good. Thank you so much mam for this wonderful lecture......🥰🥰
Firstly nucleus take the protien for the collected information from the endoplasmic reticulum then er will deliver this information to the Golgi apparatus for modifying that information and then the cells will accept that information
Mam thanku so much ❤❤ I am very nervous nd i can't understand this point but you make it easier 😊Thanku mam so much❤❤
Thank you mam for your explanation 👌👌you teachs very well 😁thank you

Yes u are right afrin🙂👍
Yaaa
Plastids are three types
1) chloroplasts:- they contains the green coloured pigment called chlorophyll.
2) chromoplasts:- are coloured plastids that give fruits and flowers their distinctive colours.
3) lecuplasts:- they are colourless plastids that help in storing starch, fats, and proteins.
