Thank you very much sir...u have cleared my most of doubts that remained in M.Sc... appreciate your efforts...best wishes :)

[@shomusbiologyofficial]

Good suggestion. I will think about it

im grateful for your work. all of your videos that i have watched have helped me. they are efficient. got a first year biology exam on tuesday. no better way to prepare for it, thank you

[@saifazmi4882]

This is good channel. Also watch Right track for NEET, best channel ever I had found for biology Student.

[@nehachaudhary239]

Thank u so much sir for such type of this vedio... It help me so much to understand deploymental biology proper..thank u again

[@shomusbiologyofficial]

You're welcome. Glad to hear that you're getting benefit from my lectures

[@amindelna5863]

you have taken extra much time for such easy topic..

[@liyakatali8662]

sir you are great sir... you are my icon sir

[@ravinikam623]

Its very good nd ur explanation is totally excellent. Make more nd more interesting lecs

[@luxmikh8821]

Tq sir it's a good channel n very important in exam preparation

[@shomusbiologyofficial]

You're welcome

[@aman9336]

In basics of developmental biology video you told that the cells determine their fate in blastula stage and now you are telling in late gastrula stage.

[@areebagul1913]

So helpful and easy to understand! Thank you so much!!

[@shomusbiologyofficial]

You're welcome

[@dhanyaas3715]

Sir all presentations are very good. Very much helpful the students. If you connect topics with expected questions then it will be too much sweet....any way thank you .....Saraswathi devi will give lots blessings to you.....

[@amritasriv87]

awesome video sir... very useful.. thanks a lot

[@ashrafmony]

How long it take to become a zygote ? whats happens within 1 or 2 days ?

[@kalpanajaiswar5025]

Thank you so much sir now this topic is clear to me😊

[@digvijaysingh6923]

its very good but i suggest u please refer some q? form csir paper which related from your topic this really helpful to student .

[@azizshah1643]

Thankx a lot sir really gud teaching style......

[@harishapatangay8121]

Very informative great content nd gud explanation keep doing more videos

[@shomusbiologyofficial]

+Harisha Patangay thank you

[@anerijoshi9141]

Do the commitment of cells in later blustula stage will be done by any regulatory factors or enzymes?

[@stayhappystayhealthy2349]

Can I refer ur videos for GATE XL? Will these videos be enough for GATE XL zoology topics?

[@meerz9343]

Thanku sit ji u r great sir ji

[@shomusbiologyofficial]

You're welcome

[@prantikbasak1009]

sir when you show in your board that upper cell having the animal hemisphere if it is in large amount in the cell or full cell is animal hemisphere in the experiment

[@sahilseikh9902]

friend plz make a vedio on different type of egg of vertribrates plz...... n thank you for your useful vedios

[@sheikhzainab4360]

sir"i want to know why cleavage is rotational in case of mammals

[@drashiqhussainmir105]

Because the first cleavage division is meridional forming two cells, thereafter one of cells will divide again by meridional division but the other cell will undergo equatorial division.

[@swapnabehera3451]

Sir what is pattern formation of cleavage ? I can't understand

[@MarkDavidSamraj]

Energetic teaching.

[@indranimukhopadhyay1879]

In this video.. we saw that cells formed from only cleavage of animal or vegetal pole gave rise to a belly piece. Then how single cell can be totipotent. Each and every cell should give rise to a proper blastula? But if it forms belly piece.. then how these cells can be totipotent? When the cells become totipotent? Please reply Sir Suman Bhattacharjee

[@saikatsamadder5472]

Indrani Mukhopadhyay Very good question madam...I am curious too...Kindly explain as I can't see any answer from Mr. Suman...I think in the video the word totipotent and pluripotent word were not utilized in proper way...See soon after the fertilization meiosis begins as soon as the no. of cells are 8 those cells are totipotent in nature are called morulla but when the cells produce mRNA, proteins, growth factors and Amino acids thus becoming pluripotent (the inner mass cells) in nature at that point it is ready to enter gastrula called blastocyst. So, if the cells are sliced horizontally or vertically really matters as the fate is decided from that point itself (the stage when the cells were sliced are important during the experiment as not discussed in the video making it complex). Blastocyst can transform into Gastrula with the help of those nutrients further becoming unipotent in nature. After every round of cell division followed by growth phase helps it to occur. Now cells placed vertically over one another or horizontally placed beside each other has its own importance for forming different layers in further Gastulation or gastrula formation via blastocyst which is pluripotent. Morula and gastrula are two types of cellular stages of blastrulation process so the answer lies in the time he mentioned that too but not clearly. What do you think about my answer kindly reply as I am not sure.

[@ambikaprodhan1875]

sir plz avoid the repeatation....

[@sangesherpa4832]

what a explanation ..... thank you :)

[@Mohabbatsingh]

Early gastrula - not committed Late gastrila - committed special function. Thanks

[@shomusbiologyofficial]

You're welcome

[@abhisheknarwal2863]

I have 1 question sir , can I ask?

[@lucygomango899]

Tq so much sir.....🙏🙏💐💐💐💐

[@shomusbiologyofficial]

You're welcome

[@arkalr3334]

Sir the mixing of the cortical region takes place on both sides of the zygote after the rotation after sperm entry as per the drawing so will the grey crescent form on both sides ? Would be very helpful if you could reply to this doubt of mine.

[@shomusbiologyofficial]

In one side mostly

[@arkalr3334]

@@shomusbiologyofficial thank you sir for the reply, so as you said mostly on one side how is this determined on which side the clevage or furrow will happen ? And in the cases where grey crescent is formed on both sides does the clevage formation take place from both sides of the zygote?
