I remember watching these videos back in eight grade for biology. Now I’m in my freshman year of college rewatching them for my first anatomy exam on my way to becoming a nurse ❤️😂

Who's here in 2024 because studying is boring so you watch this instead

Literally no one:


Pinky: "Have you ever been sitting in class and thought to yourself "I wonder what my skin cells are doing right now at this very moment'"

[kolehiyala]

I am already in med school and these videos help me review some basic concepts. I am very thankful to our chemistry teacher in my 1st year college who introduced you to us

Me: Ugh I have to watch a video... I hate bio...
*clicks on video link*
Me: Oh It's Amoeba Sisters
*gets popcorn and a notepad*

I don't even have to study this topic, but the Amoeaba Sisters are so magic that is both informative AND funny to watch! Good job as always! :D

[gavo]

My teacher showed us this channel in biology.. now im here on my own :D

[ToxicPea]

It's funny how the Amoeba sisters have only one person talking in their videos. Does that mean the second sister is non-existent, or does she edit? Either way, the content is very helpful.

I was watching this during class and I wasn't expecting a reference to portal but seriously this video helped me a lot on the assignment I was doing thank you

[imsoquirky]

For the past year, I've been struggling so much with biology to the point where I just gave up on the subject. But your videos are A LIFE SAVER! I honestly never understood my teacher in class but that was until I came across your videos. Thank you so much.

[randomsomeone]

Wow perfect timing! I have a test on this tomorrow for honors bio

[Ace_with_cake]

Came just in time for my cell biology final tomorrow morning, can't even begin to say enough "thank you" in appreciation! Just exactly what I need in solidifying my grasp on this. <3

[nicks]

I have my middle school trimester exam on this tomorrow! Please send prayers! Totally wish we watched this. P.S. I binge watch these videos. LOVE YOU AMOEBA SISTERS!

My nephew had a brain injury last year and his doctor told us some of her neurons had “died." I beleive he was referring to the fact that he had lost brain cells in effect to the incident and will, more than likely, not get his neuron cells in return as easily. After watching this video from 7:57 to the end, I now understand what his doctor is referring to. Thank you for this video, Ameoba Sisters. Keep doing what you do.
