    Thanks for the hard work sir. I am struggling with biology so hard. If without the vid, i would have taken abt half an hour to one hr to understand this instead of 7mins vid long. Thanks in advance for the more coming bio videos.

      Don't worry you are not alone. Form 4 syllabus is very heavy. It will be better in Form 5. The key is to not give up and keep going! 💪🏽💪🏽

    Thank you for this video. I am just struggling with one thing, I wish someone could help me. Is the secondary oocyte that is penetrated with the sperm cell or the ovum?

    • @gowridurairajan3166
      @gowridurairajan3166 Рік тому

      The sperm will penetrate the secondary oocyte (immature ovum) first so it can complete meiosis II to become an ovum. Then, the sperm's nucleus fuses with the ovum's nucleus (fertilisation).
      Hope this helps!!

    Sir what is the origin of follicular cells?

    • @togexinu
      @togexinu 4 місяці тому

      Follicular cells generate from ovary itself , see once primary oocyte is present in cortical region of ovary many cells starts to proliferate or surround this primary oocyte , all these cells are presnet or comes from stroma , these stromal cells geta flattened and surround the ooxyte hence forming follicular cells

  • @SingamAddabey
    @SingamAddabey 8 місяців тому +1

    I have a doubt sir ovum need to be fully developed before contacting with sperm so when sperm comes in contact with oocyte then it's lead to zygote right then when will ovum forms

    • @togexinu
      @togexinu 4 місяці тому

      Basically ovum doesnt need to be fully magured once soerm comes in contact then the egg becomes fully mature , because usually when theres no sperm secondary oocyte is present , so until theres no sperm it cant get converted into an ovum

  • @alexanderurquhart7496
    @alexanderurquhart7496 Рік тому +1

    Haploid does not mean half of the chromosomes. It means single chromosomes. This is a MAJOR misconception that proliferates because of so many videos using the term incorrectly.
    Hap comes from Haploos (Greek) meaning singular. Meiosis does indeed reduce the number of chromosomes per set in half. However, only diploid organisms will produce haploid gametes after meiosis, as 2 chromosomes per set divided in half equals 1 chromosome per set, AKA: haploid. A tetraploid organism undergoing meiotic division would thus produce diploid gametes. An octoploid organism would produce tetraploid gametes, etc.
    PLEASE STOP describing Haploid as half. THIS IS NOT CORRECT and proliferates confusion in students!
