Why do we (and animals) need to drink water?
In: Biology
There’s something called osmosis, which basically means that our cells need a certain amount of water through their membranes to function before they shrivel up and die.
You can see this in dehydrated plants how they become limp, and hydrated plants are firm. But we need to drink water and not just absorb it.
All our cells have functions and organelles inside them, which float around in the cytoplasm. The organelles are sort of like our organs, which do things to keep us alive. And the cytoplasm is watery fluid that lets them move and function.
So tl;dr without water, our cells cannot function properly.
