Dr. Marshall refutes the commonly held idea that cells are just bags of watery enzymes. He runs through his “Top 10 List” of unexpected and amazing things that individual cells can do. These including growing to be huge, navigating mazes, and performing feats that seem to belong in science fiction.
Speaker Biography:
Dr. Wallace Marshall is a Professor of Biochemistry and Biophysics at the University of California, San Francisco. He is also a Director of the Physiology Summer Course at the Marine Biological Laboratory in Woods Hole. Marshall’s lab is interested in how single cells count and measure to determine cell size, number and organization. They have developed the single celled giant ciliate Stentor coeruleus as a molecular and genomic model organism for these studies.

The whole time Marshall is talking I just think, I hope he never stops, this is so great. Do not run out of crazy facts about cells, Marshall.
I was blebbing the whole video
LOL Incredible. A science fiction writer wouldn't dare to introduce such ideas into a plot because no one would believe them.
Thank you for preparing and posting this video. It was a revelation.

Is the same with the atom, we believe that atoms are stupid boring, but not, matter is live, the atom is very complex and live, read mathis miles milesmathis.com/ or you want go deeper in the hole of the rabbit read "occult chemistry of 1908". The implications are amazing.
Good list by Tukkers, I were about to mention a few but only one missing: Valonia ventricosa

Samesies
yeah, wonderful short lecture. and yet still so much to discover about cells, we can easily do 2hr+ video full of amazing facts about cells.
Lag Duck I’d watch it.
Please do, I will definitely see it
I showed this to my 6 year old son and he loved this video so much! I was watching my son as he was listening to you, it was the cutest thing - he would pause the video at times to understand/define any word he didn't understand. Sometimes he took notes, but most of the time he would draw the definition and color it! He was doing this for 4 hours.
You are an excellent teacher and very easy to listen too. My son subscribed to you.
Thank you :)
Good for you for Allowing your son to watch an intelligent video, if it kept him entertained for 4 hours he understood enough not to be bored by something that was incomprehensible to him. Ignore any knocker who suggests otherwise. It’s incredible that he drew some of the pictures. Encourage his interest. Don’t dumb the child down to the level of people who would suggest that he doesn’t understand at least enough to hold his interest for 4 hours.
As an adult with no background in biology, I don’t understand all of it and, like your son I frequently need to stop look up the meaning of a word. Even then I know I don’t fully understand the subject matter of the video however, my general knowledge has been increased by viewing the lecture.
Early exposure to topics is excellent for children’s learning. Young children don’t know that they’re supposed to be “grown up” before they understand the world around them and so incorporate what they experience into their general learning .
Good for you. Allow him watch whatever is good for him and stirs his interest.

This is what learning is!! Not forced tests and lectures, but fostering/encouraging natural interests. True learning will always take its own course. You go little kiddo! :)
@@wip8889 haha ya got me! I am awful. Really though, this sounds like some bullshit
cellular robbery: "give me your chloroplasts or I bash your nucleus in! "
Grab the 'plasts and bleb the hell outta there!
My cells thank you sir, especially the ones watching youtube.
Watery bag of enzymes is the best description of cells I've ever heard
Oh god now I'm going to spend the rest of my life wondering if there are toxoplasma in my brain.
Just assume yes, make your peace and carry on. Some things get worse with contemplation:-)
Mr.Y theOrangutan, get a blood test.
“A toxoplasma test is a blood test that determines if you have serum antibodies to the Toxoplasma gondii parasite. It's also called a toxoplasmosis test. Your body only makes these antibodies after you've been infected by this parasite.”
just get rid of your cat
@@pansepot1490 Huh, thanks.
thats the toxoplasma talking
I thought the guy in the left bottom corner was an example of a Toxoplasma sufferer.
I thought the instructor was a Taxoplasma sufferer
LOL
He certainly is. Never seen him drive, but he matches all the rest. He also loves cats.
@@DrSid42 cats are great. Mine just turned 4.

We have only scratched the surface of the cell wall 😁
Oh my bleb
Simply amazing. Great lesson.
What an eye-opener this video is. Thank you very much!
This is incredible. Thank you to Dr. Marshall for this brief and accessible presentation on these quite extraordinary cellular phenomena.
Excellent, I like the way this guy clearly explains stuff.
I like his beet red face haha
Mind blown! Awesome video. 3 billion years of evolution before multicellular life began. That's a lot of time to develop creative structures and complex behavioral algorithms! I had no idea just how huge a single cell could grow!!!
No evolution, stupid ! Creation !
I can't remember the last time I was so interested, amazed, and focused for a 20 min lecture. This short "10 facts" session completely blew my mind!
The most value for time video around! I felt like having a University course in ten minutes!!
Although I was already aware of cell's complexity and beauty, this video made me respect cells even more. Great lecture!
beautiful composition! as a grad student in a computationally heavy neuroscience program, the comment about the limits of individual cellular computation hit home hard. It brings to mind current models for neural networks, simple perceptrons with simple error functions that are able to output solutions to protein folding and all kind of stuff! a seeming contradiction that models can produce complexity, but reality consists of something much more complex than a perceptron. super cool video!
Love this talk ~ so fascinating and well presented
Each section is full in scope strangeness and diverse complexity
Thank you Dr. Marshall
& iBiology youtube
Bravo
Wow. Thank you. This is incredible!
01:20 at first I thought he said "no one knows where all this shit comes from"
LOL!! I can't tell what he said...
I knew about toxoplasma, but wow, I lost count of the things I hadn't known before. What a splendid video this is.
Outstanding lecture! I've never skip your classes.
Amazing! And more amazing is to believe that all of this comes from a simple blob that built itself from random matter and energy, and formed genetic information that casually changed until becoming human. Perplexingly stunning and awesome!
@John Carboni ...and only someone with less intelligence than a doorknob would think it was magic-ed into existence by an invisible sky wizard. Stop trying to claim science proves your delusions.
Thats's amazing. A critique I would like to make is: the computational step, for example, in solving the maze is porbably more in the diffusion and the density of the molecules than the cell then does follow to find the solution. What I mean is that the cell start with the maze already solved to some extent. One way to solve a maze is to simulate a "flooding" from the exit then when the water reach the entrance you just follow the "flow" or the height of the water in the opposite direction. The first step (simulating the flow, or the diffusion of the molecules) is computationally expensive, following the flow is computationally trivial. In the same way cells might simply follow the density of certain molecules and grow in that direction eventually reaching the exit.
The same thing applies to the subway example where the problem is pre-solved simply by chemistry and diffusion of the molecules.
Great comment.
Yes, it's less amazing than it seems at first glance.
I found this absolutely fascinating and informative. To me, sci-fi like X-Files isn't all that outlandish. Especially when this guy says we just scratched the surface. Looking forward to more videos!
Really interesting, I had no idea of 99% of the cells shown in this video. Nature is so amazing. Thanks for sharing!
Awesome! I'm new to Ibiology channel... very cool videos!! This top ten is very well done thank you.
Wallace back at it again with the valid knowledge
A few years ago, in the gap between two jobs, I arrived at the conclusion that I knew almost nothing about unicellular organisms and had to penetrate the topic. After some two years I ended up having collected many thousands of photos of protists and algae of all different types, meticulously arranged in order of the newest cladistics to be found in the web. By the way, I got somewhat familiar not only with their evolutionary history but with plenty of incredible facts about their life cycles, cell structures, sizes, ways of metabolism, mobility, vision, etc., many of them fresh discoveries of science. There is an absolutely amazing microbiological universe everywhere around us and within us, hidden to our eyes and to the awareness of most. So complex that we are still at the beginning of its exploration.
Thank you for propagating that knowledge, you brought in some great examples.
One of the best concise summary videos.
Top notch lecture, really enjoyed that, thanks for posting
Wow!!! that was really cool Wallace, thanks!!!
That was absolutely awesome :) thank you
Thank you that was absolutely fascinating.
We were never taught biology in school, just general science, which was more about things like vacuums and electricity. Not a cell in sight unless it was a battery.
I have never thought about the things that you mention and it sort of makes sense now.
Interesting video. Clear and concise explanations. Thanks great work 👍
Amazing, I have been getting into microbiology after a new RUclips channel about it started up. "Journey to the microcosmos", now I have been watching these lectures and its so fascinating.
So you have a choice of what to do with your God-given curiosity and brain power. Have fun and thank God forever, or thank your great great grandfather chimp and study for a few years and then die forever. God wants you to live forever to study ALL OF HIS CREATION FOREVER.
Tay100 , ak-ak, ook ook, eek eek eek. That's chimpanzee for have a banana and chill. So if someone grabbed you butt and threw you in a cage with the other chimps and primates, no harm, no foul? Planet of the Apes come to life.
What on.... Will leave you both to it, have fun fellas.
Tay100 , About as idiotic as your comment sounds. I watched a video that showed an evolutionary link bust made from a couple of teeth. Really? An entire head with primitive ape-like features from a few teeth? Are evolutionists that gullible?
I know it and you know it that there is a on-going conspiracy to shut down the world-wide discoveries of ancient civilizations building stone structures and buildings that defy our modern abilities.
Long before I became a believer on God, I was a pagan-catholic. I didn't accept evolution for lack of evidence. What I did see was clear evidence of grand-scale genetic engineering just as we do with domestic animals.
Then came Chariots of the Gods and that was my answer with hard proofs. It was scoffed at, but that means fuel to my mind. The ancient accounts of Spanish explorers all pointed to 'sky gods' that came down to help primitive man move civilization along. Sky gods, you say, not just any old martian aliens, but gods. Hmmmmm... Interesting 🤔.
Then I had an opportunity to study the bible with an amazing lady who knew it backwards and forwards. But I would use only the bible, nothing else. That didn't mean I came to the truth-hunt unarmed. I bought a bunch of different bibles to add to a few I inherited. I also bought a Hebrew/Greek - English interlinear translation of the old and new testaments. I spent two years studying all religions and comparing them to evidence. I bounced my new biblical ideas off friends, employees, and family (no internet at the time). I filled binders with bible studies of every topic.
What I found changed my life for good. I found out about creation and the creator. I found out that all man-made religions are a lie. I still know that evolution is a farce. And my original suspicion of Carl Sagan's theoretical life and physics was 10% science and 90% snake-oil, has just expanded over the decades. Evolution and theoretical science teamed up in a board-room somewhere to develop their business model. Carl Sagan failed to create life, but he did open the door to us finding the miracle of life and the living cell. NOT what he intended. But the die had been cast, and the atheist connection was forged.
The bible is more amazing than you could comprehend. God set it up that way so he could control it and who 'got it'. A back-drop of what's behind it would take a book, but why? I know the bible and people whom God chooses will learn the bible. That suits God, so it's good for me.
Tay100 , BTW, I'm no idiot. I did't have the money or the backing to get into college, although I wanted to become an aerospace engineer. So I settled for a technical degree in industrial design. Within 6 years I was a design department head and within 10 years I started my own engineering business in the oil & gas refining industry. Tough/good times, feast/famine, no degrees, no post school training, hard work, etc., but I survived 30 years on my talents as the envy of my constituents by making more than any of them, but with their degrees.
When I decided to start my business right in the middle of a bust, my fellows said I was crazy. Three years later I was making over 6 figures and never looked back (while they were still laid off). So when I am called a looney for believing in God the creator, 'been there- done that, got the t-shirt'. I'm used to it. I'm retired now, but I may re-start my hydrocarbon process school for plant operators.
I can visualizing sitting there n a board room while listening to the evolutionists and theorists conspiring on how to increase their market shares.
Best explanation ! Thank You Doctor Wallace Marshall !
Thank you for this elucidation! As a layman, I truly appreciate the lucid presentation, which in a way makes me realize that what I am is in fact what I am at the billions (or is it trillions) of my cell levels! 🤔😄
It further emphasizes what Yoga talks about when it refers to "Praaña" (life-stuff is a crude translation) or "naadi" (pulse, for a crude translation) in our various nodes.
All the iBiology videos are great but this is my favorite one by far!!
By proving cells are much smarter than people think they are you also prove that we are not "greater than the sum of our parts" as some people have said, but are merely equal to the sum of our parts working together
This brings us closer to understanding sentience and higher level thinking
Fascinating. Thank you for this!
Outstanding man!!! Thank you!
Great great job !! Thank you !!
Thank you, sir.
Fantastic lecture.
Fascinating and interesting talk. Side note: In 1986 I suggested to my sister-in-law (top grad from her med school class, undergrad biology) that cells could take up bits of DNA or other internal components of other cells and utilize them. My suggestion was based solely on the fact that cells are little chemical machines which often use the same or similar components with similar chemical structures. She said I was "crazy".

amazing lecture, thank you!
Great presentation , thanks for sharing !
Awesome! All in one take too!
Really enjoyed this excellent presentation.
Captivating information.
this is one the best youtube suggestions ever.
I love learning this. Thank you
Great presentation! All of these mechanisms of the cells and their organells plus other functions such as protein motors, prove that there is, "Intelligent design"!
This is amazing, thank you very much
There's so much crazier things that cells can do, admittedly. Fun video that taught me some new things!
Many youtubers will cut the video in editing after every sentence, creating a choppy mess that I find very distracting. Dr Marshall teaches us good info for nearly 20 mins straight with little to no cuts. Teachers should be paid so much more. Thank you sir.
Superb Lecture !
Great lesson! Thank you!
That was excellent. Thanks.
Very interesting and well presented.
Wow, this is so interesting. Thanks!
great video! thanks!
no joke, i though this was going to be boring and bad. But the professor was relatable and made you feel that he was not biased nor narrow minded enough to discount some theories in light of others. I enjoyed this presentation.
Wow.. Thanks for sharing.
Thank you. Very interesting!
Great lecture
Excellent! For years i have been gathering what i call "Remarkable Facts About Life." Right now it stands at 84 pages long. Now i have ten more to add!! Thanks for this. I was waiting for you to discuss the bdellovibrio. Perhaps you should do "Another ten things cells do."
That was amazing. I am using this lecture for home school. Thank you!
nice! Home schooling is the way to go, regular school kills children's passion for subjects when home school can be amazing at igniting it, especially when you show them amazing things like this. I bet your kids will do well, you seem like a good home schooler that will fill them with amazing wonder for these subjects. Good for you!
Great stuff Wallace!
It is amazing to live in a time where science fact is so much more compelling, interesting, and mysterious than any science fiction we could imagine.
Or any Neolithic goatherder mystica;l skyboss bullshit.
Amazing stuff thank you
WOOOW This video is really fantastic! WOOOW
Ok I wasn't prepared for this to be this cool
Very interesting. Thanks.
Great video!
Nice video, thanks!
"There's nothing more extreme that you can do than to explode."
True dat.
Wonderful video!!
Thank you!!
Wow every natural creation is beautiful magnificent so much to discover and learn
I’m not into Biology, I don’t know why this was in my recommended, but I watched the entire thing and my mind is blown (it wasn’t the Appressoria in Magnaporthe grisea, but maybe the Taxoplasma..)
Cell biology is amazing, didn't realize cells can get so big.
Great video.
Wow, about the tunneling WBCs. I was always taught they migrated from blood though gaps between endothelial cells, for instance in the inflammatory response.
This is so incredibly cool
This was insane.
Probably the best video I've seen on youtube in years.
I was always fascinated by the cells inside oranges, just the thought of a cell, something you think of as microscopic, being so big that you can see with the naked eye. But somehow it never crossed my mind to actually google it and see what the biggest cell can grow to.
As you can imagine, this completely blew my mind.
Love this video
This was fun to listen to.
Wonderful. I agree the complexity of the cell is underestimated. I remember evolution timelines that day things like for the first billion years or so not much happened until multi-cellular life developed and then it became interesting.
😁 Quote of the day: “There is nothing more extreme that you can do than to explode...” - what an awesome countdown top ten video!
Very interesting!
Very, very interesting!
As a, Lay-person, I find myself searching for the Words that might otherwise express my fascination for your Work and these must suffice: Thank you, Sir, for this most excellent summary!
THANK YOU
So interesting !
