- The lower half of Mr. Andersen's head explains why cells are small. This video begins with a simple geometry problem and ends with a discussion of Allen's Rule and reasoning for the microscopic nature of cells.

POV: You’re in high school and your biology teacher is making you watch this for homework.
no
Yes
Santeri Joseph yes
I've been grinding this biology homework for way to long, shoulda just done it when it was assigned
Yuh
went from learning why cells are small to how if you live farther from the equator the more spherical you'll look
The captions saying why cells are small:
Our cells are small because we want to maximize the surface on the outside. And the reason why, is that we have to get nutrients into the cell, oxygen. We have to get waste products out, like carbon dioxide. And so if we can make ourselves really small then we have a large surface area. And also that oxygen then doesn’t have to defuse so far to get into the cell or carbon dioxide diffuse so far to get out.they can’t be too small or else nothing could fit inside it either
This man is an excellent teacher! I wish he taught me High School Biology.

"Mr. Anderson... We've been expecting you."
I liked the demonstration in the beginning which helped tie the concept neatly in my brain. Great stuff, thanks!
I'm happy to hear that the videos have been helpful. I would encourage you to visit my website and fill out the translation form. We have had trouble sending translations to hotmail addresses and so you may have to grab a gmail account. Sorry about that.
Bozeman Science yes
here i am, december of 2018 and i'm watching this video because of my teacher
So interesting! Althought I already knew about it, you helped learn some new facts and גevelop a different perspective on this process.
Thank you! My science teacher showed me this video at school and I still didn't understand it so I watched it at home to help me study for a last minute test! Thank Again!
You the homie, Mr. Anderson
Fr tho
this helped me so much! your display is very helpful in understanding why it's important cells are small. thank you!!
When the comments section is all about people who watch this for help in their homework and all you get is praise, then you are the Pride of the people.
Had to watch this for a class. Thank you, you explained things very well.
This isn't mine craft mods
really????!!!
This actually helped a lot thanks mat 🤙🏻
That was really helpful 😊
It was helpful, but I think some people might find it offensive how you said "If you're smart, you should be thinking..." if they weren't thinking that.
sjw
i was offened !1!!1!!1!!1!1!1!1!1!1!
A YEET AND A YAP IS A YIPPITY SNAP!
Very nice video, just one comment: it is not that the Inuits wanto to maximize their body volume or the Massai their body surface, it is natural selection process that selected those phenotypes
This actually helped answer a question. It was simple and to the point. He should make his other videos more simple and to the point.
great demo!!!
i watched this and a few other thigs and i think my test will go quite well ive been doing reasearch all week but its always better to hear someone talking about it than just reading it
so did you do well on the test??
Loved the demonstration way♥️
I’m sent here for a science assessment and I still don’t understand he didn’t answer the questions I have... can anyone help!?
cells are small because if they're to big they can't get all the things they need and it's to hard to maintain
5:16 WELP I GUESS IM NOT SMART :(
lol sameee
Great explanation!
Thank you so much for this
My class needed this for our demonstrations in class
*just casually has a beaker full of bark*
great video
Why are cells small? 4:45.
For easier understanding turn on the captions
that's a cool way to compare volumes
4:45
@TiaKhosla lol I can't exactly remember bc I commented this 5 years ago but basically the title of the video is "why are cells small" and this is the part where he says "cells are small because..."
@TiaKhosla haha it was fun actually, took me back to high school bio class 😂
@TiaKhosla I think it's ok~ I am in my 3rd year now of Uni yep :) in elementary education but I'm actually considering being a science teacher so it's funny I am brought back to this video ✌️😌
@TiaKhosla aw haha thank u ~ University of Florida! 🐊

Hello Bellarmine AP Biology students!
Very interesting.
@MrZoider You are correct, but that is a bit illogical because "shrink rays" don't exist
Thank you❤️❤️❤️
Your explanation takes the unwarranted assumption that there can't be larger cells with the same surface area ration to a much smaller version of the cell.
That's because it's not an unwarranted assumption but a property of 3-D space. As an object's size increases, its volume grows much faster than its surface area, meaning the surface area to volume ratio decreases rapidly. It's called the square-cube law actually. Here's a good video on it:ruclips.net/video/qoM17ikreio/видео.html
Classy Sir.
well explained
Your videos rock!
They're minerals
I’ve been watching these videos and damn yall must be adults by now😭😭, a whole generational video
thank you
If your watching this video you are getting SWOLE by the minute. -Patrick Gaines
Thank you got it 😊
Awesome!

I think you mean the opposite thing. You mean big surface area and small volume, right? You might want to correct that. Anyways a helpful video, as usual!
This kinda works like transistors in a CPU? like 12nm or less is shorter distance for electrons to go through a smaller area... correct me if I'm wrong
awesome!!
Ive been wondering if it was possible to create gigantic cell in a laboratory by meddling with the cell's genes so that we could better see what's going on there.
i was sent here by my biology class.....
same
Nice. ...
If you don't want to watch the whole thing because your teacher made you, than skip to this part 4:45
I don’t wanna do this assignment
whats 'the' reason, then?
not me
Had to watch this for school.
How unfortunate.
anyone has a link to a proof through geometry on this?
مافهمت شي
At 5:20, it should be "infinitesimally" small and not "infinitely" small
anybody here from Mr. Lyons? hello from Nease!
What period do you have him? I have him third
Yo Is anyone here from Ms. Kelly's bio class?
He shows us one reason for cells to be small (not "the" reason)
Yow this video help me learn more things in science cause my grades in science are so small its like my grade in science is very very low grades that's why I watch videos that is so im portant in my school #this is the most awesome video
this is ray allen's rule? the basketball player?
so everyone’s teacher had them watch this ?
Its also Calculus =)
Anyone here from Mrs.Griffin
John 14:21
So i am not fat, i just live far from the Ecuador.
Nuclear weapons 😮😮.....so thatsvwhy they are so powerful
Face reveal?
OMG WOW JUST WOW
Anyone from Bain's Bio class feelin me here?
well cells are very microscopic that not even using a microscope
did you see the troll face at 1:31
Any of my niggahs from Mrs Garcias class here?
wow
This make no sense to meat all. This is awful.
2011
Jesus fucking Christ help me get out of this
jk
Anyone from mrs.harlands class here ? XD
Amoeba sisters are better
Get to the point…
