[@googleclassroom6647]

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.

[@MrRuelTuition]

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! 💪🏽💪🏽

[@marwababiker7457]

how does meiosis 2 give two n cells if it itself was an n cell as it did not undergo interphase

[@sunlightsaharan3606]

Everything was explained with details except follicular layers like xona pellucida, corona radiata.

[@nandinikannan2794]

You explained so well sir thank you...😊

[@MrRuelTuition]

I'm very glad to know that. Thank you!

[@SingamAddabey]

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

[@mabelyokeke176]

I watched several youtube videos for this and still didn't understand it
Now I understand this. Thank you

[@MrRuelTuition]

I'm really very glad to know that! Thank you 😊

SIR ? AND WHAT IF THE SECONDARY OOCYTE IS NOT FERTILIZED WHAT HAPPENS ?

[@Grace-ll9zc]

Thanks sir😁

[@MrRuelTuition]

Menstrual cycle coming up next Saturday 😊

[@vireenharjai1004]

@@MrRuelTuition rlly? My menstrual cycle is gonna happen on Saturday 😗

[@geriosbadran5821]

thanks a lot what is the primornal germ cell ?

[@seemadubey4909]

It's basically a stem cell, which will eventually turn into gametes.

[@xyz-km3pm]

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]

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!!

[@SingamAddabey]

​@@gowridurairajan3166 It would have been clear when it said on video

[@lozadakeanjay7947]

can i have the picture please?
i was going to use it for my report

Ok boss 👍🏿

[@xannaancabdiraxmaan1661]

so does that mean the ovam is zygote

[@user-ln8ug6zy6d]

I never knew anything about this before watching this video but after it oh my God 😭 I learnt more than enough thanks a lot ❤😊

[@frzdytheconsumer8094]

1:25 **ATRESIA

[@rachelsire2546]

So In meiotic event an ovum produces an ovum after it has been fertilized🤔🤔??

[@kimsyaf8144]

3:04 cikgu kenapa dia 2n

[@watchaccount]

you say oocyte 2 has 23 chromosomes. Where are the chromosomes of the second polar body from? mitosis?

[@geriosbadran5821]

i think the excess of the chromosome goes to the polar body

[@alexanderurquhart7496]

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!

[@tccrosbyy]

Cut the man some slack. Most students are specifically learning about humans, so I think the descriptions are quite fitting and the least confusing. That being said, thanks for the info.
