Why are cells small?

#2

idk, I'm outta school right now(pink eye) but i just missed my science test. had i been there for 42 minutes longer, i could tell u!

#3

For the same reason your penis is small...

Just kidding, but in reality, I don't know.

Good question.

hello twisted mmagun

cos they need to be cos how else are you gonna fit liek hunderdz of em on your body??!Q!!

because if cells were big, we would be big, annd there would be no space on earth:-)

#8

If they were any bigger I'd consider them some kind of Japanese pocket monsters.

#9

thats a stupid question!!!!

they are small because thats how cells evolved.

Cells are the basic structural and functional units of life. As life on

earth has evolved into organisms of varying complexities, two basic laws

of nature have dictated why cells have remained so small.

Shorter is

faster. This is true both in terms of diffusion and in terms of chemical

and electrical movement. By minimizing the the distance between a cell's

nucleus and and the numerous proteins and organelles that it must

constantly regulate , a cell is maximizing the speed in which

intercellular communications can take place while providing the ideal

conditions for diffusion: a vital function in the life of a cell.

Like

wise, the surface area and volume of a cell are directly influential in

the efficiency of the cell's nutrient absorption and waste expulsion

processes. Since the cell membrane of a eukaryotic cell is its only

source of nutrition, it's surface area must be large enough to allow the

cell's organelles to receive the materia ls it needs. This is done by

maximizing the surface area to volume ratio. By using the surface area

and volume equations for a sphere(4¹r2 and 4/3¹r3) you can estimate the

modeling the growth rate of the surface area and volume of a sphere on a

linear graph it's easily discernible that as the size of the sphere

increases the ratio of surface area to volume dramatically decreases

until finally the volume of the sphere surpasses the surf ace area.

Simply, by minimizing its size, a cell is maximizing the speed at which

it can communicate, the rate at which diffusion can occur, and the amount

of surface area at it's disposal.

What kind of cells are we talking about?

#12

They wouldn't be able to transport proteins/ATP easily if they were larger. It takes 2 ATP to transport pyruvate into the mitochondrial inner membrane to undergo Krebs cycle at the microscopic size cells have. If they were bigger, they'd be inefficient.

#13

Well yeah, homeostase wouldn't work, you'd die.

Though technically, you could never really be alive.

#14

Because no one loves our murders and rapists.

#15

What kind of cells are we talking about?

batteries, i believe

#16

Some nerves are massive. Not all cells are small.

#17

Why are cells small?

Why are you so big?

#18

maybe cells are big, its just there is other stuff that is bigger.

#19

they are that way just to piss you off.

#20

Because when Microsoft programmed excel.. they wanted them to be..

#21

because it only looks small to us, because we need 513684646 of them to live.

#22

An egg is a cell, and that's not really small is it?

#23

it's pretty relative really?

#24

The rate of diffusion would be to slow if they were bigger and then cells would need to have transport systems made of cells which would be to big.

#25

Beat me to it...

#26

it's to with surface area to volume ratio. As the cell increases in size the ratio becomes smaller.

#27

it's to with surface area to volume ratio. As the cell increases in size the ratio becomes smaller.

I think what he is trying to say is it is small in order to maximize the surface area of the cell. Which is the main reason that cells are usually small.

#28

It's objective really. They aren't small compared to atoms.

We are big compared to cells. We are small compared to planets.

We are big compared to cells. We are small compared to planets.

#29

if all the cells in the universe grew 10x all at once, would we even notice?

#30

(_) care cup, its empty.

btw this is a really dumb question.

why are tv bigs?

because people want/need them to be.

n.n;D

well yeah cos we'd all get 10x bigger

#32

Seems pretty big to me.

#33

Seems pretty big to me.

Hot.

#34

what kind of cells?

Jail cells or the type were made up of?

they aren't they're actually huge!Why are cells small?

but we're even MORE huge, so they seem small to us.

i feel really fail for knowing a lot of words in there and what they mean...

god i hate biology

#37

Seems pretty big to me.

Awww... You beat me to it!

but yeah

but how do you know cells arnt HUGE!

but were just HUGER!

eh?

think about that!

or not... whatever

Edit: i just realised i was beaten to that aswell

FFS!!

i gotta think of something else now... ¬¬
