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...

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
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.
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 :)

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

Thnk u so much mam....u r simply amazing 😍😍😍😍😍😍
Very helpful videos
thank uuuuuu for wonderful lectures
Wow ma'am ur the best ❤❤

Mam.. Thanku for this video.
Very much helpful to me
Wow mam u are a very nice teacher
Best faculty
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
why root hairs get curled?
Because rhizobium bacteria secretes a chemical known as nod factor
👀
@@sonalisonkusle2776 thanks
Bless you mam ❤
Mam you are zn we are enzymes you stimulate many enzymes (many students)😁😘
Mam rhodospirillum is anaerobic photoheterotropic and azatobacter is aerobic hetero and bacillus anaerobic chemoheterotope
Very nice
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

Mam please make a video on nif and nod gene
Mam,
Please upload a video on anatomy of plants
thank you so much ma'am
super classes mam... please make more videos..
How fixation takes place in nonleguminous plant?
It's aweeome
Helpful video lectures mam....
thank you soo much maam
thanks a lot maam
It's really nice
awsome explanation mam
thanku mam it was really helpfull
is there any interaction between Rhizobium and roots of the host plant
Yes. There is
Mam why root hairs get curlled🤔🤔
Because infection thread enters the root hair
Tq Mam..
Good teaching
Mam..plz upload a class of genetics of N2 fixation
Thank you ma'am
thank you ma'm :)
Mam, Please Upload The Video Of Characters of Angiosperms.....🙏🙏👍
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 :)
why not root hairs enlarge in size?
thank mam
4:20. 10:33
Madam please increase your volume in the video it's very very low while hearing it without earphones it is really a big problem
Mam u are awesome
What is the root curl? ??
But Nostoc ana bena are free living baceria please explain
Mam plz.... Make videos of chemistry on elementary quantum mechanics ....
Mam, do lateral hairs contribute to rhizobium infection
Tysm....
maza aya
NYC one mam
An -ero- bic haha I love that sound .....thnks ma'am 🥰😘
Rhizobium is rod shaped microb.
mam thank u so so much for your clear explanation and we are very lucky to have such wonderful mam like u
After 4 years, i can appeal you to change the marker inks at proper time
Maam plz bacterial genetics ka video upload koriye
Too much helpful lec ... Mam😆😆😆
Mycorrhizae fungi please
Love u Mam .
Thnks alot Mam u r suprb 😆😆😆
