Hooke and Leeuwenhoek were two of the first scientists to use microscopes to study the microscopic world of cells. Hooke coined the term "cell" after observing the tiny compartments in cork, while Leeuwenhoek discovered a variety of living creatures in pond water, blood, and other samples. They contributed to cell theory, which states that 1) all living things are made of one or more cells, 2) cells are the basic unit of life, and 3) all cells come from other cells.

6:10 (Drawing horns on Virchow) is kinda satisfying LOL
So you're telling me we doing all this because of Robert Hook
Yup.
ugh
😂
Like??? 🥴
Even if it wasn't him someone would have probably done it but just later and so we would have had to study this but less
Isaac burned paintings of Robert
Me: only memories that on the exam
I legit laughed when he draw horns on Rudolf Virchow lol BAHHHAHAHA
Hahaha, me as well
me too! lol!
same lol
Isaac Newton burned the only painting of Robert Hook...So savage
so funny
*Mitochondria are the powerhouses of the cell*
Goodness, I could still remember our teacher drilling this sentence Into our brains😭😌😂
right
this guy is a legend in writing with a mouse
He has a drawing tablet or something
@@norasmith8266 probably
@@norasmith8266 Is their an arrow if you are using tablet? He is probably using a mouse.

Man I wish I had this video when I was in school. Keep up the good work Khan!
blitzwaffe Khan Academy should replace school.
blitzwaffe Sal Khan took education when he was on 60 minutes and Charlie Rose.
Im actually using this to review for my bio exam 😁
Spencer Key it did! We home school and use Kahn for a lot of it! Lol
im so tired of biolgy
Same
Interesting. Issac Newton burned the last picture of Robert Hooke.
Painting*
Sub-Zero that's what i was wondering about..
I didn't expect that plagiarism was already that relevant before! Hahahaha!
I'm watching Khan Academy since it's quarantine. Hahaha!
Lol. You put horns on him!😂
🤣
Robert Hooke studies Biology,Physics and Chemistry. Isaac Newton burned his picture due to the fact that when Isaac discovers the law of gravity and on why the planets move, Hooke claimed that because of his study of physics Isaac Newton was inspired by it.
Very interesting; thanks for posting!
Thanks!! I have to make a presentation about this on Friday. This has helped me so much
How did that presentation go?
@@zenmeteor9545 bad I got a 6/10
@@heyyou5680 oof I’m sorry
@@zenmeteor9545 heheh don't be, it was 3 years ago. Still made it into medical school :)
@@heyyou5680 Nice!
I really like Kahn’s videos for the most part however it’d b great if in your educational videos you researched ahead of making it how to properly pronounce the persons of interests names.
thank u sooo much this video helped me to clear my all confusions
My favorite is when Virchow get's horns drawn on him
😂😂
I am very confused about the timeline because according to the module... Anton van Leeuwenhoek's discovery emerged first in 1653 before Robert Hooke in 1665, and it is said that Zacharias Janssen was the one who created the microscope in 1590.
Content of the Module:
In the late 1500s, spectacle maker from the Netherlands, named Zacharias Janssen, invented the microscope. In 1600s, Anton van Leeuwenhoek, a Dutch shopkeeper who had great skills in crafting lenses observed the movements of protists (a type of single-celled organism) and sperm, which he collectively termed “animalcules”. In a 1665 publication called Micrographia, experimental scientist Robert Hooke coined the term “cellulae, " shortened to “cell” for the box-like structures he observed when viewing cork tissue through a lens.
Thanks for educating people!
+Bruce John Wayne the way he is educating people makes them uneducated.
My favorite part is when Sal draws horns on Virchow
Welcome , STEM students:)
Might the term "Animal-cule" actually refer to the "animated" nature of the protists?
Its nice
dude. The last portrait of Robert Hooke was burnt by Isaac Newton!?!?!? Proof he was a rebel.
Good
good
the most interesting thing about this video is the fact that he's writing with a mouse
NICE
Yes good
some people says virchow is the first who know that all new cells arise only from cells that already exist
because he had horns
Wish we did what you did to Vichow to Thomas Edison, They'r practically the same. R.I.P Nikola Tesla
I can't imagine what the guy who discovered that sperm was alive was thinking... he was like hey... you know what I want to put under the microscope?... 😅😂
The pictures are in my book I like your video oh and it's Virchow so yeah lol😜
Happy Birthday Antoni :3
don't forget Robert hooke
JK
JK=JUST KIDDING
@SHOOK彩菜 lmao
But that's just a theory, a game theory
Watching this in 2020 👁👄👁
Nice
I want Thai subtitle!!
cool vid
My teacher gave the credit to virchow in our lessons
Thank you
Does this stuff ever make you think there is a God? Everything just seems to purposefully to be spontaneous

Who is discovered(researchers) the term of eukaryote.
Please hurry to hurry give me answer,this my Q.
Edouard Chatton
Robert brown (botanist) first described nucleus....
What has the germ theory vs cell theory to do with Covid-19?
sir, if all cells come from other cells then how did these Cyanobacteria
come into existence at all which was the first living organism??
Almighty created them with the words, "Let there be cyanobacteria." 😉
pls add some more info otherwise gud
Khan Academy, where Joaquin Phoenix is teaching me math and sciences.
Wow
this is not the truth, it's just a theory
kevjtnbtmglr This is the truth.
Definition for a Theory "a supposition or a system of ideas intended to explain something, especially one based on general principles independent of the thing to be explained."
A Theory is backed with thousands of evidence to prove it's true, like the Theory of Evolution, we evolved from Apes to Humans, and all of it is backed up with good, clean evidence to show it's true.
The Theory I think you are getting mixed up with is a mere guess, however a Theory in scientific terms is a hypothesis backed up with evidence, and can be explained, unlike the Theory you refer.
Trolling successful. Objectives complete. Back to my cave I go.
BTW. theory simply put means "explanation" of the facts (observations)
You're meaning for Theory is just a blurb for the whole content of definition, not in depth.
Nice try trolling, but sorry you failed, and what do you wish to accomplish by pathetically trolling?
OLA K ASE LE DI DISMEGUSTA
Why are there horns on Virchow head
He plagiarised Remak's work, which is naughty.
Yeast infection is
The devil horns took me out! lol
Thats good stuff
Text book-virchow
Kia Yehh Video Urdu Men Translated Hai ??? Plz ans sir
Rober hook
Honestly this kind of ideas and theories drives me mad. When will science confirm that everything was crafted by ALLAH and that our knowledge is limited to HIS will. How arrogant can u be to suggest and teach a idea that everything was created from a single cell and humans' ancestors were monkys or catfish and build up science based upon it.

ya tu english ma ha
@ 6:10 😈😁😁😁
I'm just pointing this out, but I'm pretty sure it was 38 trillion cells
whos sperm was Leeuwenhoek studying though?? did he do the deed and keep the sperm himself?? for science ??🤣
А чого це англійською?
Virchow looks like an uwu girl
A “Yee cell or a U cell?”
1665
This is a minor point, but still... The lecturer (even at the prestigious Khan academy) should probably learn to pronounce the names of major historical figures relevant to the subject matter of the lecture BEFORE PRESENTING THE LECTURE.
