I wish I had a dollar every time my cell divides
I wanna be a quadrillionare
so friking bad
bruno Mars is shaking
I'd get $45
@@y4diy Ummm fetus?
bruh if I had a dollar for every time my cells divide I wouldn't be here cramming for a test. smh
I watched this in my hs bio class to prepare for tests like 4 years ago, now I'm in college and I'm back for round 2
Xamm Jo how’d it go?
"maybe someday, i'll do a biolo-graphy about you" is the most inspirational thing i've ever heard

+Rachel Lee I memorized metaphase the same way!
You absolute LIFE SAVER
Thank you!
how for prepare though
THANK YOU RACHEL LEE, you're not going to believe this, but that's my twin sisters name!!!
guess we are all bio students whos got their exam coming tomorrow.
pretty much
yep.
Today****
+lame o Sadly... This is too true.
+lame o unfortunately this is the most true thing i've seen all day. Good to know we're all in the same boat i guess
All the comments from 3 years ago, while I’m here in 2019 bc I’m writing my exam tomorrow😭
Parth S. ahhh how did you do and same
Parth S. Same
you're not alone
lol, I have a test tomorrow
@@m.mbanditry7133 same:)
When you’re watching this in 2020 and you realize it’s from 2012
Shout out to everyone cramming for tomorrow! Good luck!
goodluck
Hey, that's me!
ayyyy thats me now. Canadian exams!
Thank you so much! :)
HAHA I'M CRAMMING FOR TODAY
2 hours of teaching and understanding my teachers failed to do was accomplished by you in 10 minutes
always lol
+Dulcie Gibbons uh huh
same here
that prof pic is everything
i feel you fam
Stop reading the comments you've got a test tomorrow morning!
Fortnite Arcade 😭😭😭😭😭😭😭
i feel personally attacked
I literally have a Bio final tomorrow.
My reaction:
How did you know?!?
Nani!!!!?????
I've got a presentation tomorrow morning............
Easy way to remember Prophase, Metaphase, Anaphase, and Telophase.
Please (P) Make (M) Another (A) Twin (T)
Ryan Baluja Prison Meals Are Terrible
my teacher taught
I (interphase)
P ark (prophase)
M y (metaphase)
A unts (anaphase)
T ruck (telophase)
as you should RB. as you should.
i usually just call it IPMAT , but that's a really good acronym
I just think of someone peeing on a mat... Pee MAT. shortened to PMAT... just me?
I remember the different phases like this:
Prophase: Pro- 1- first phase
Metaphase- M, Meet, where they meet in the middle
Anaphase- A, Apart, where they're pulled apart
Telophase- T, Terminal, the final stage
Thanks that helps a lot xx
No worries xx
Amani Rashid of just think PMAT
Amani Rashid nice one. 😎😎
thank you ;o; look at you, helping people from the future
These videos are the only reason I actually understand Biology
Isha Perry hahah same
same
I watched this vid before my AP Bio exam in high school, and 2 years later im watching it again for my college biology class😂 THANK YOU HANK AND YALL GOT THIS!!!
who's watching this during quarrine 2020 because of Covid-19???
Me. It's spelled quarantine.
Me
No, I'm in quarantine because of the spanish flu..
@@markusbjrnberg4796 Noice
I am cause I don't know biology at all that is why I am learning
You teach this waaaay better than my teacher did. Thank you!
My teacher dint even teach us. She just gave us homework.
goldengurl20101 know how you feel man
Eirin Rhiona MacLeod Beese yep...same here smh
i agree and class be loud
Mackenzie Miller I agree pasta does taste quite delicious!
When james charles stubs his toe "Mitosis!"
Lmaooo
your comment is so underrated lmao
Now I can't stop hearing "my toe sis" everytime someone says mitosis.
solid comment 8/10
I hate you
Watching it 10 years later seems so nostalgic. Thank you for all you do CC!
I've stopped watching my normal assigned videos and started just watching relevant Crash Course episodes. Go Hank!
I got a History exam on the 27th and a bio exam on 28th. Gonna binge watch crash course.
That is exactly why I'm here.
Joy Zheng
Ahem...
...yea, you're right. Good luck
***** ...holy... Good luck. Ouch. I'm glad I'm not you. Hope you ace at least three of them.
holy...
Caitlin Quick I like to eat and watch this guys videos man. I also feel that it helps to watch these videos and then read the chapter because it helps in visualizing what is happening. I like looking at pictures, but they will never be like a good video. Biology is tough man a lot of people I know dropped the class, damn pansies you gotta keep your head up and learn.
David Ortiz Agreed. All the memorisation sucks, but it's worth it in the end.
thank god for this video i needed this for my bio test this week
+suncutie12 same...
I have my test right now :p
+suncutie12 My test is coming this Tuesday haha
+Brandon Best Yeah me too
tmrw for me
Hank is 1. A good actor 2. Has the benefit of cuts 3. Has no bored or disruptive audience, meaning he has no major distractions from his energy or focus 4. Is (apparently) using a teleprompter (he is looking slightly above the camera) 5. Has perfectly integrated images and videos to keep interest. 6. Has a snappy soundtrack and sound effects. 7. Is able to use a carefully written script with perfectly polished delivery (because 1, 2, 3, and 4).
These are all advantages your ordinary teacher probably lacks. So please, enough "Hank is better than my actual biology teacher!" Hank is something totally other than your teacher, he is a professional presenter with a team. It's kind of like saying "Tom Holland is more charismatic than my actual high school friends." Well yes. Yes he is. But also. . .movie magic / cinema skills. If your teacher had a professional video team and coaching, they may or may not achieve similar results- it is a totally different genre.
None of this is to suggest anything bad about Hank or crash course. It is an amazing product done with high values, a passion for teaching and a very strong work ethic.
Yes, what you describe are the attributes of any good teacher who spends appropriate time in preparation.
Love that, especially the Tom Holland comparison. Hank is not a high school teacher - that's why he's able to fill in the gaps so effectively.
HE IS NOT THE HERO WE NEED BUT TRULY ONE WE REQUIRED
No one explains it better than this guy
Stfu Trash Can the Hank brothers cannot be matched by any other.
Reale Pineapple do you even English???
RUclips gives me more than my actual teachers tho...LOL =>
i think we are all forgetting......Paul 'Bozeman Science' Andersen......He could give the green brothers a run for their money
Got a bio test in 2 days. *Braces self for all-nighter studying*
+Inayah Cee
Same.
+Inayah Cee This is what it's like to be in the land of men XD
Aimee Jeman Why?
Lol, the land of men (as in humans) is like really dangerous and wild. But it's a test... nevermind. moments gone :P
+Aimee Jeman I can agree, Im in year 10, last day of school, bio test. Greatttt
who else has a bio final tommorow
✋
+Sofieethedork o. I had a bio final two months ago, I passed with the help of crash course
+Sofieethedork o. I have one in 2 days T_T
Ariya Ziauddin ahaha good luck man, i had mine last week, think about it, everyone sits the same exam, if shit comes up on it you havnt really heard or studied much of, dont worry thatll be the majority and so the bell curve will help you out:) Think about it, if you study most of the course quite well and you only answer 80% of the questions (mark wise) you have a higher potential to get around 90% of that 80% which equates to a low A or B+, especially in bio where the average mark is around 55% or some shit, so make sure you know the major concepts really well and in the exam dont get scared if theres a 1 marker you cant answer and you can see everyone else can!!! make sure you hit the 4,6,8 markers easily mate and youll be fine!!!
Me :(
I'm not procrastinating as much as everyone else here ...I actually have *two* days before my exam ;)
i have 4 !!
I have 3 months xD
Shoutout to all the kids who are just studying without a test coming up
You have just explained what my professor couldn't in 3 weeks, in 10 minutes concisely. Thank you.
On behalf of Science teachers everywhere, Thank You! I have literally seen the "light bulb" moments in several students because of your videos. Our text books are no where near as up to date as these videos. Love my co- teacher Hank Green;)
Omg. A miracle just happened. I understood half the unit in 10 min 😭😭😭
i always come here before for my test. I learn more in ten minutes then i do in two weeks with my school teacher.
Virginsuicde sadly true lol
2 hour lecture explained in 10 minutes. Awesome!!
i can tell that was a waste of a good 2 hours, right?
like, you could have spent that much time SLEEPING!!
I love looking at the comments and reading all these ppl who are like "thank you I almost failed my test if it weren't for you" and I am like "look at these idiots who need RUclips to study" then remember why I came to the video in the first place...
Jake Gagnon you're an idiot
😂😂😂😂 I felt the same way
RIGHT?
I needed Hank Green to explain Mitosis. My life is complete now.
Something that might help is remember PMAT
P-Prophase
M-Metaphase
A- Anaphase
T-Telophase
1:20 slow it down to 0.5 and he sounds drunk LMAO
Sounds like the drunk guy at the bar trying to give you relationship advice! hahaha! This is so legit!
fciprian trust me... lol
Avaline Kress Hahahah I had to do it, hilarious
Avaline Kress hahahahahahahahaha im weakkk
Avaline Kress Get drunk and everyone sounds drunk. I like that method more.
you explain this better than my teacher does and she has degree in biology. you dont understand how much me and many other viewers appreciate this channel!! we love you hank!!!!
EVERYONE IN THE COMMENTS SHUT UP, your jokes are distracting me 😂
Crash course is love, crash course is life
Who wants him to be your science teacher?
Oh!Yeah!I literally love Hank!
The Gaming Army me
He sort of is XD
@@Gealamusic me
i mean me
Remember PMAT people
ikr
prophase metaphase anaphase telophase... damn tomorrow exam's gonna be lit
More like IPMATC
I dont get it?
Interphase, Prophase, Metaphase, Anaphase, Telophase, Cytokinesis
who else had to watch this for school since we're in quarantine?
I don’t have a test tomorrow this is just how my teacher is teaching with social distancing
Yup
Omg ! I have a Bio Honors exam tomorrow & I am literally going to watch this over and over again. You explain it 1000x better than my teacher. Thank you !
if you're watching this,
it's too late.
Fuck you.
Allan Ochoa fuk ur shit boy
Allan Ochoa Never too late, still 15 hrs until the exam.
Mythrunes you know about the AS biology
[Melon] Mike As bio is ez.
Who in their tests just remembers this dude pointing at you going : liver failure , MITOSIS!
lol
This guy literally knows everything, every field of learning, i find him
its actually two different people, his brother covers English and History :)
@@JamesJones-fk9id ohh yeah i discovered that but still i will just give them credits for that
you legend this taught me quicker than my teacher lmao
Annabel Condon omfgg sameees
another way I remember Prophase, Metaphase, Anaphase, and Telophase is Pass me another tequilla
omg yes xD
YOU ROCK
Or Punch My Annoying Teacher
oooookkkk, so u mean that when the cell gets fat it borns clones? that was easier than i thought.
IPMAT
Interphase: copy’s
Prophase: nucleus membrane disappearing
Metaphase: copy’s line up in the middle cell
Anaphase: copy’s are pulled apart to different sides
Telophase: new membrane forms around the chromosome
Cytokinesis: they divide into daughter cells
I hope this simplified every thing and helped you, let me know if 8t did :D
I would like to thank you on the behalf of us that struggle with learning difficulties such as dyslexia and dysgraphia. These videos make the hours of lectures that seem mind boggling to us, so much easier to understand. The way the information is broken down in the simplest form is honestly a life saver and an amazing resource. THANK YOU
Comment and like if you think Crash Course should do Physics
+Tyler Goodchild (tg228) Never gonna' happen ;)
YES
What type of physics (I do support it)
Good god, yes! love physics
Wish granted
i've got a Biology exam tomorrow that i've pretty much accepted that i'm going to fail
im in the sam boat i brought sunscreen
I'm right there with you
Did ya fail?
I was up so late watching videos like this and revising that i overslept and missed the fucking exam
Liam Crosswell omg i just got to do an essay on it
The only reason I’m here is bc of my online assignments due to the corona virus :/
Me three
I'm watching this not because I have a bio test, but because I'm a senior in high school who is stuck in quarantine and can't learn properly without a teacher explaining things to me
i would like to personally thank this episode for saving my grade
You guys haven't felt irritation and embarrassment until you've been in a massive biology class and the teacher keeps talking about you and your twin. Not a surprise that I didn't fucking learn anything.
Trevor Spencer Victim complexes are embarrassing.
rob stark umm wow that was unbelievably rude.
I am so grateful for every video from Crash Course. You guys have helped me through so many classes!
What did one daughter cell say to the other daughter cell when she stepped on her foot?
'Mitosis!'
I regret nothing.
@@ply-animations3365 XD
Boooooooo
Where is the "my toe sis" joke has no one commented yet please I need to hear it
+Eren Mortel What did the cell say to his sister when she stepped on his toe?
Ow, that was my toe sis!
+Eren Mortel where"s my toe sis?
YOU HELPED ME PASS MY MIDTERMS and teach me everything that my teacher didn't thank youuuuuu so so so much. You're awesome.
You guys are the best! Thank you for helping me through my second take at college - prereqs for nursing school and prep for my entrance exam!!! Your videos are amazing and I couldn't have gotten A's in my classes without them.
Also, just FYI, the anaphase section actually starts at 8:47 :)
Just got a perfect score on my lab exam because of this video, we had to identify the different phases of mitosis under a microscope. thank you!!
P- Passing
M- My
A- Algebra
T- Test
In Prison Meals Are Terrible :)
Except this is biology O.o
+Joshua Evans Or a variation on that -- In Prison Meals Are Terribly Cruddy :P
I actually remember it as "Please Meet Ana Tonight."
lol we should just compile a list of all the different acronyms about this :)
Lol my identical twin and I are watching this because we are studying for our AP bio exam, Shout out to You HANK!
Thank you! You made biology make sense and have been getting 80's on my bio exams 😍
This is so helpful when studying for lab practicals. Thank you, crash course!
Hank is the reason why students pass their classes.
Ur fat
Watching this because I have a quiz tomorrow D:
I have a final tomorrow
just watching yet another one of your videos prepping for an exam, just wanted to say thankyou I think you are an amazing teacher and you make things simple to understand and funny with your dry sense of humour lol, you have actually taught me so much through college and now through my university degree thank you!! sending love, light and blessings to you :)
Saw this months back for my unit test and here I am again, for my finals. These videos are honestly such a blessing. ❤
Just discovered this channel and it basically saved me and my entire biology class as well. Thank you!!
With such limited times to study for finals, these crash courses are life savers! Thank you so much 😊
Thank you for explaining this so well! 5.5 hours of bio lecture this week < 30 min spent watching your videos
Hey, just want to say... really love the videos and your way of teaching. You keep it fun, which is SOOOOOOO nice.
This video just saved my life, because I have a biology exam tomorrow and my teacher didn't really teach this. THANK YOU.
I discovered your RUclips videos last semester, while taking Human Anatomy and Physiology I, & I've been watching you, for EVERY unit we cover, ever since! I've even introduced your site to my study group, & we all LOVE how you break this down for us!!! Thanks for making learning FUN, & interesting, so that the info actually sticks in your head! =)
Hank, I could listen to you all day long- love what you're doing! Thank you!
your explanation really works. What my teacher couldn't do in 3 hours for seven days you did in 10 mins today. Thankyou so. much.
I see a lot of comments about how this video is better than their teacher etc. I'm lucky to have a good bio teacher and Crash Course to help me ;)
Hey Hank identical twin here! Just finished writing my notes and this video is a perfect supplementary resource! BTW my bio teacher shows us your videos all the time XD
I slept through both semesters of bio, so thanks for saving me as usual, Hank.
These are honestly super high quality videos, they almost make this stuff interesting. Super helpful for studying tbh.
Really enjoyed this video, It was fun to watch but educational. Not many videos can say the same
Biology exam Monday!!!
haha yeah i'm using this for my bio midterm on Wednesday :p
Bio exam on Friday and Tuesday
Dana Thomson tuesday and friday??? how??
Lol good luck everybody ;)
:-)
I wish I discovered your videos 2 months ago, I have only watched 4 videos but already you have helped me improve my grade in Biology!! THANK YOU THANK YOU THANK YOU!!!
0:00 The birth of Hank and John Green (colorized)
"Crash course!!" You weren't justa kidin'.
But I really like your videos. I'd don't even recall seeing anyone else attempt to explain the biological processes. So, thank you.
I'm just curious...how did you become so knowledeable in bology? Are you just a student, or do you have a degree,or work within biology? Just curious. I'm very impressed.
Hank has a Bachelor's in biochem and a Master's in environmental science.

This video helped me a lot. Got finals this week and I was still unsure about this topic. I understand this topic way better now.
Crash course helps me out so much. I am BEYOND thankful that this is a thing...
Just incredible. Im glad I found this video. I plan on showing it to my students Tuesday.
I - not very "I"nteresting.
P - chromosomes first a"P"pear
M - chromosomes line up in "M"iddle
A - they move "A"way
T - you almost have "T"wo

Thank you so much
I wish that the Interphase portion of this video was more detailed. Where is the G1 phase, S phase, G2 phase?
I don't think you replied in time...
Either way, yes. G1, S, and G2 are not part of mitosis. It's all under the cell cycle which within itself mitosis is a part of. They're a part of the cellular cycle *alongside* mitosis.
The real evolution is me having watched this exact video in seventh grade and now watching it as a sophomore in college... life moves fast and biology is still complicated :0
Love your quick videos. I like to use them to supplement my longer teaching videos.
10 million billion = ten quadrillion. 10 thousand billion = 10 trillion. Since, you know, this is clearly the most important part of the video.
Who's watching this before their Bio AP Exam?
Yes
*puts hand up and head down*
Favour Adeleye I'm watching this for a biology test.
I'm done with the class now, I miss bio...
This subject material is always relevant! I watched this same video in high school, then again in college, and now, again in medical school. Never stop learning. If you miss bio, take some bio related classes!
I love watching ur videos. Got my human bio exam tomorow, Have given up on watching the class lectures. These series have saving my life aha, :')
I love you, crash course.
You have taught me more than all my professors.
