Right, so here we're thinking about cells and their environment, and in particular how animal cells are different than that of many other groups.
00:10
And so this question is pretty open -ended, why animal cells survive without the type of cell walls in other organisms.
00:22
So if we think about plants, plants have a very turgid or stiff cell wall, and they need that for structure.
00:32
Without that rigidity, they would just sort of flop on the ground.
00:38
And having that structure to grow tall gets them more sunlight, which is, you know, there's more energy and nutrients.
01:00
Humans, however, you know, our cells don't quite have that same structure.
01:04
But we get our energy and nutrients from mobility.
01:11
Okay, so humans, we go and we go to the food and find it.

Nowadays, that just looks probably like ordering a cheeseburger...
