In and out, in and out. Staying alive is about doing things. This very second, your cells are combusting glucose molecules with oxygen to make energy available, which keeps you alive for another precious moment. To get the oxygen to your cells you are breathing.
Breathing is an answer to a very hard problem: How do you get the resources that your cells need to survive, from the outside, to the inside of your cells? Every living thing has to solve this problem and the solution is surprisingly different depending on one of the most important regulators of life: Size.

Great video as always! However, let me actually answer the question in the title "How Large Can a Bacteria get?". In 1999 a non-phototrophic sulphur oxidazing Bacterium called 'Thiomargarita namibiensis', which translates into 'Sulphur pearl of Namibia' was found off the coast of Namibia. The Bacterium was measured up to 0.75 mm in size, which is large enough to easily see by the naked eye! Isn't this amazing?!

for anyone coming across this comment, the way that Thiomargarita namibiensis gets around the diffusion problem is by having a large vacuole in the center of it. So basically all of the cell's "insides" are in a layer closer to the surface of the cell, while the actual core of the cell which is harder to reach by diffusion doesn't hold any of the "important" stuff.

These videos are just insanely good. I had never ever thought nor known about the concept of DIFFUSION before. And these types of very clear videos with superb graphics make it possible to understand. This channel always amazes me at explaining such crazy complicated stuff. Honestly, when you get to understand these concepts, you realize that life is such an impossible thing to achieve. I thank this channel for making me grasp the insane nature of our existence. Let's not take if for granted (although I will do that anyway in the next 3mn).

Edit : To the team, I think it would mean the world to say hi in the Reply’s. I know it would make mine. Have a nice life, and I hope you are all doing well during the COVID season. Reasons I love Kurzgesagt 1. The Narrator. I swear if you fire them, I will strike. Well, probably not, since I love this channel, but still. 2. The Animation. Every scene is something to look at, it is stunning. Amazing job animation team! 3. The information. The fact that you all show your sources, while also make an easy to digest, animated, video. It is amazing! 4. The Availability. You could get this on Hulu or Netflix. No doubt. It could definitely be on Amazon Prime. But the fact you make this free shows how much you care about educating the world. And mostly the youth, you can't deny it. 5. The demographic. I am 13. I love watching these. My grandpa is 65. He loves watching these. You have made a series that anyone can watch and love. 6. The conclusion. I am going to say it right now. You are the new Bill Nye. Take your seat among the champions. Carl Sagan, Bill Nye, and Neil Degrass Tyson, just to name a few. I hope you see this, and you know that you deserve every subscription and more. Edit 7. The Music. Check the replies to see who said it, but I totally agree. The music is amazing. Edit 8. The Team. I can not stress enough how great everyone on this team is. Everyone only thinks about the Narrator and the Animators, but there are so many more people than that making each and every episode that we all love.

A teacher of mine had a neat way of demonstrating this. we simply gathered four of us. one to represent the intake of the cell, one to represent the outtake of the cell, and two others to represent the intake and outtake of nature or the world outside. We started close by each other, and our goal was to pass a ball between each other. It was a very easy ordeal near each other, as we could simply pass the ball with a simple outreach of our arms. But then she got us to stand further apart, requiring us to throw. It got harder, we had to toss the ball and took time by aiming and sometimes we had to go pick up the ball. Next she got us to do this from the corners of the class room and it got mega hard, the ball almost never took a direct trip and it regularly dropped, and we had to take extra time with aiming. In hindsight, it wasn't exactly the best demonstration, perhaps a 'timer' of 5 seconds could have been added to represent the cell's time left alive before lack of passing the ball kills it, but we got the general idea. It at the very least explained to us why cells would rather become multicelluar rather than become just a big ol' cell.

*Fun fact :* the length of all your vessels added up together is around 100k kilometers while earth circumference is only 40k kilometers , meaning that u can wrap your vessels around earth 2 times and a half !!

It's actually a scary lot like programming when you really think about it. A lot of modern developers wouldn't understand because they don't realise the amount of syntactic sugar, which would be a full human for example, while older developers had to still "build" that human with all those tiny clumps of cells. In the end, the syntactic sugar (modern functions you can just call upon whenever you want) is actually just a wrapper for a lot of pre-made functions. So, very much like a 'human', said functions still go back to the very roots of programming, which is 0's and 1's... Bits. These bits get clumped together per 8, to make a byte (compareable to a cluster of cells). Every pre-made programming function really isn't anything other than if statements and loops. "If 1 then " and "if 0 then", repeated thousands of times (loops) to eventually pretend as if "stuff just works". Much like how we don't actually see our bodies working and how many extremely basic stuff happens on a small scale, to eventually connect it all into one big scale working thing, is how syntactic sugar works for programming.

The sugar desolving animation kinda hurt my feelings as somone who had chemistry but it was still great. I love the amount of energy you put into your illustration!

i wish this is how school would teach us things, as school teaches one simple thing and makes us remember all the useless and wasteful bits, but this channel teaches us a lot of things that are easy to remember, simple, and actually related and useful to the actual thing and topic

I watch these videos not to learn the science (that I already know,) but to understand the pedagogy. How to teach it to children. These videos are pretty slick, more appealing than what we got in the 1970s school documentaries. PS: "Kurzgesagt" in German means "concisely said," and this channel certainly accomplishes that. Gut gemacht.

Idk why, but this video just makes me smile. Maybe because of how these organisms are suspiciously happy, or the amount of automation in animals. Anyways, this video in particular just makes me smile

I've learnt so much Biology in a video of Kurzgesagt more than I learnt it at school, thanks Kurzgesagt! Life is a miracle, doesn't matter what's your size... tall or short, big or small. And we should be grateful for it.

It's cool how so many people understand how the concepts explained in your videos work. Too bad I can't say the same for Minecraft's Redstone community, I don't get how people don't understand how it all works.

I wonder what would happen if diffusion for an organism became ridiculously sped up? Would their bodies become super efficient, or maybe they just turn to paste as all the atoms in their body flood into the space around them?
I am happy that people increasingly recognize scientific dissemination, and information in general. And congratulations to this channel for the enormous quality, production, content ... I love physics and more people should know it too! A hail from Brazil
apenas mais um Diogo.
Sou do Brasil também! Este canal na minha opinião é um dos melhores em divulgação científica da internet, tanto pela animação estilizada quanto pelo nível de didatismo e profissionalismo.

The information on this channel became very handy during these pandemic, when a lot of news sources try to mislead or produce panic in masses. Thank you, honestly. Would you believe if I said this information helped me to calm down my friend? almost got depressed ( not the right word but you know what i mean). Interesting, isn't it?

While I understand why, so this is not a complaint, I always get surpriced by ads on this channel. The content is so professional that ads seems beneath them. At least my mind expects ads from more serious sources than what I'm used to seeing on a vlog, let's play or reaction video. Kurzesagt is basically awesome.

Humans are the largest bacterias/bacteriums on Earth, we eat up everything and spread like cancer. xD

@BillAnt We're not composed of a single cell though and cancer is not a bacteria. Very bad comparison.

@BillAnt Humans are living things and living things spread, if we didn't some other species would have done the same things as us just in a slightly different way.
I didn't get the joke
@BillAnt cancer doesn't spread tho. It's a non communicable disease and it isn't caused by bacteria.

@I didn't get the joke it does.Cancer can metastasize like hell and kill the body by killing the brain/lungs/heart.We spread like hell too.There's barely a place where we are not present.

Cheeringly enough, my mother's a biology teacher, and she uses Kurzgesagt videos and other internet content for education instead of plain old textbooks, it's so that her class is the only one where textbooks are not required... She showed this vídeo to her class when seeing the respiratory system part. Everyone got an A+ in the test.

Still the question in the title was not answered... I just looked it up. The largest bacterium ever discovered, at least, is 0.1-0.3 mm in diameter, sometimes attaining 0.75 mm. It's called Thiomargarita namibiensis and it is large enough to be visible to the naked eye. I'd call that pretty impressive!

There is a single celled organism that is far larger than 1mm, in fact it's even bigger than an insect. It's the Caulerpa, a kind of green Algae. They can grow up to 12 inches, but do this by using specialized evolved organelles that imitate plant structures like stems and roots. So a bacteria might be able to get larger but would need to evolve some very specialized organelles.
