In this video we will cover:-
All flowering plants show sexual reproduction.A look at the diversity of structures of the inflorescences, flowers and floral parts, shows an amazing range of adaptations to ensure formation of the end products of sexual reproduction, the fruits and seeds. To a biologist, flowers are morphological and embryological marvels and the sites of sexual reproduction. Much before the actual flower is seen on a plant, the decision that the plant is going to flower has taken place. Several hormonal and structural changes are initiated which lead to the differentiation and further development of the floral primordium.

Amazing. I am a finance professional in practical life but this video transported me back 40 years when we slogged in biology. Amazing clarity and amazing approach. I have watched the entire playlist in Mathematics and it is hard to believe a person having complete command over both biology and mathematics.
Keep up the good work.
True sir 💯💯💯
Some people are just amazing with multitalent
Boon to have a teacher like this ....

It's so difficult for a teacher to teach all the subjects of class 11 and 12. But ma'am has proved this wrong. I am surprised how can she able to teach all the subjects easily and betterly
Ma'am, excellent explanation👏🏼👏🏼. I usually can't sit and watch an entire class in one go but urs was so easy for me to watch.. And l did not even want to pause it 💞💞.
Thank you soo much..🥺

I was really mesmerized how can she teach all the sub soo perfectly
Hands off mam❤️
Could you make a one shot video on biotechnology please? You're videos make everything crystal clear for me.
😢😢
Mam, please make the lecture series on all biology chapters.
Because many of the students are dependent on your lectures as you teach in a very very amazing and mind-blowing way.
Yes mam I can't find all the chapters teach by you🥲🥲
Mam... you are great
You always explains us by animated videos....
Thanks God for giving us an Talented and genius mam for us.
15:44 rose is polypetalous
33:55 The misconception that four microspores are produced in each microsporangium likely stems from a common example used in biology textbooks but in reality in each microsporangium numerous microspores are produced through the process of microsporogenesis. The exact number can vary depending on the species and environmental factors.
41:48 Amazing,!🤩🤩 Every point crystal clear. Thank you mam!🙏🙏

Amazing ....no need for coaching for different subjects.....coz only a single teacher is enough to make our concepts crystal clear in every subject....🔮😊🎀
Teaching using diagrams is too cool..... If anybody is aggry with this then please like
Mam you are unbelievable literally my all topics are crystal clear and the important thing is. in the minimum time you have done. it thank you😊

You are all in one ma'am. Great☺️
Mam thanks a lot
I can easily catch your explanation. I'm the kind of student who gets bored during studies but your teaching helped me to love biology.
Thank you 🌸
Very stimulating lecture n brilliantly taught . Very interesting case studies as well which made for interesting class discussions. The lecturer's teaching is well organized and presented, which helped me to accept the new knowledge quickly. I am happy with the content of the course, like the case-based approach.
