All right, so you may have wondered why are living organisms made of so many cells? why not just a few large cells to make things easier? well, in order to understand why things are made of of so many cells, you have to understand surface area.
00:17
So on the side over here, well, that's not going to be helpful.
00:22
On this side over here, we have a box representing a cell.
00:30
And on this side over here, we have four boxes.
00:34
Representing multiple cells.
00:36
Now, both of these examples have the same volume.
00:42
They take up the same amount of space, but they do not have the same amount of surface area.
00:49
The surface area is exactly what it sounds like.
00:51
It's the area of the space covered by the surfaces of the structure...
