So that other people don't get confused, what actually happens to the bacterial cells when they enter the cortex. Because ma'am here has wrongly taught that bacterial cells are of types. There's only one type of bacterial cell on entering the cortex and going through modification. When they enter, they get modified into specialized cells called bacteroids. How? Here's how: These bacterial cells first get surrounded by a plant-derived membrane called Symbiosome. Nodule formation takes place which finally leads to the formation of these bacteroids. So, then we all know that inside these nodules, nitrogen fixation takes place and as ma'am says here, that these specialized cells(she is actually referring to bacteroids only) have thick walls for creating an anaerobic condition(so that the enzyme Nitrogenase can work). So, Bacterial cells simply get modified in to bacteroids and nothing else. So don't get confused. Whatever properties ma'am here talks about are mostly (on dividing them into two bacterial cells, wrongly so) about bacteroids.
Mam, I have no words to explain you..... you are one my inspiration. May God bless you.. I pray for u from the core of my heart,honestly... As today it was my exam.. I rocked only because of you.. Wallah mam you are great...

Madam.. Rhizobium transform into only bacteroid, which is y shaped cell that fixes nitrogen... There are no other forms of nitrogen fixing forms of rhizobia... Plz refer once again
Right. There's only one type of cell after modification. And that are bacteroids. They are the very same specialized cells she is talking about in both the types.

Mam, answer plz All N-fixing organisms are a. Symbiotic heterotrophic bacteria b. Non-symbiotic heterotrophic bacteria c. Non-symbiotic autotrophic bacteria d. Symbiotic autotrophic bacteria

Yes because cortical cells are stimulated to divide and form nodules because of cytokinin(which promote cell division) secreted by bacteria and auxins secreted by plants Hope that's helpful :)

Mam we really like your explanation
Thanks ma'am for this amazing video!
Leg hemoglobin occurs in cytosol of nodule cell,,,globin part synthesised by plant genome,,, heme portion synthesised by bacterial genome,,,,,,,
Very nice ma'am you make the concepts clear .. and very understanding class. Thanks a lot . Love your classes
Yes mam
Thanks mam u are great as like as alakh sir...
Your explanation is really wonderful. ..easy to understand and I can grasp your lecture instantly
🌹Thank you mam for detailed view of this topic👏
Nice explanation...Ma'am 👏👏
Mam no words to thank u keep going it will help many people
your videos are very helpful

Mam,
Please upload a video on anatomy of plants
Mam rhodospirillum is anaerobic photoheterotropic and azatobacter is aerobic hetero and bacillus anaerobic chemoheterotope
Mam please make a video on nif and nod gene
Mam.. Thanku for this video.
Very much helpful to me
Thnk u so much mam....u r simply amazing 😍😍😍😍😍😍
How fixation takes place in nonleguminous plant?
Mam you are zn we are enzymes you stimulate many enzymes (many students)😁😘
Wow mam u are a very nice teacher
Very helpful videos
thank uuuuuu for wonderful lectures
why root hairs get curled?
Because rhizobium bacteria secretes a chemical known as nod factor
👀
@@sonalisonkusle2776 thanks
Wow ma'am ur the best ❤❤
super classes mam... please make more videos..
Mam..plz upload a class of genetics of N2 fixation
Mam, Please Upload The Video Of Characters of Angiosperms.....🙏🙏👍
Bless you mam ❤
is there any interaction between Rhizobium and roots of the host plant
Yes. There is
thank you so much ma'am
Ur way of teaching is super👍.. I am plant pathologist from Chandigarh. Keep it up 👍
Best faculty
Very nice
thanku mam it was really helpfull
Helpful video lectures mam....
Mam plz.... Make videos of chemistry on elementary quantum mechanics ....
thank you soo much maam
Mam why root hairs get curlled🤔🤔
Because infection thread enters the root hair
mam thank u so so much for your clear explanation and we are very lucky to have such wonderful mam like u
Mam, in class I was told that nodule formation is initiated by cytokinin and auxin...I am confused..
Yes because cortical cells are stimulated to divide and form nodules because of cytokinin(which promote cell division) secreted by bacteria and auxins secreted by plants
Hope that's helpful :)
thanks a lot maam
It's really nice
Mam, do lateral hairs contribute to rhizobium infection
Good teaching
why not root hairs enlarge in size?
An -ero- bic haha I love that sound .....thnks ma'am 🥰😘
Madam please increase your volume in the video it's very very low while hearing it without earphones it is really a big problem
awsome explanation mam
thank you ma'm :)
But Nostoc ana bena are free living baceria please explain
It's aweeome
Thank you ma'am
thank mam
Tq Mam..
maza aya
4:20. 10:33
What is the root curl? ??
Rhizobium is rod shaped microb.
Mam u are awesome
Tysm....
After 4 years, i can appeal you to change the marker inks at proper time
Too much helpful lec ... Mam😆😆😆
Love u Mam .
Thnks alot Mam u r suprb 😆😆😆
Maam plz bacterial genetics ka video upload koriye
NYC one mam
Mycorrhizae fungi please
Any 2024 aspirants??
