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.

Some people are just amazing with multitalent Boon to have a teacher like this ....

Mam u r my savior! I knew NOTHING in physics chem and bio but then ur teaching made it so so so much easier. I believe that it was because of all that visualisation and stories which made me understand every concept of the chapter. Thank u so very much.

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.
its really a great video and a real time saver that the whole chapter can be completed in an hour but whereas my teacher take an hour to explain just the parts and structure of a flower really appreciatable ma'am great work ma'am!! fr
Ye ek revision series hoti h school mei deep mei pdhte h fir ye video dekho bhut ache se smj aa jata h
