@dakingisgman And you need not worry about me failing biology, I already passed my exams last year. ;)

Although I did pass with only a 7 for biology. I just don't think it's because of cohesion that this system works. In fact, if I remember correctly it had something to do with adhesion. But I could be wrong. :)

@dakingisgman I think you misunderstood me. :) I fully understand the principle of cohesion and its traits, I was just quickly trying to say the following:

Even without cohesion, when an underpressure starts building up (in this case because of evaporating water, but you could also be sucking air through a straw, for example), matter will start moving. Wether that be water inside a plant, or air in a straw, basic principle is that [something] is being "sucked" upwards, because of underpressure.

@RavenMischke What are you talking about? The hydrogen in water is attracted to the lone pairs of electrons in the oxygen atoms in the other water molecules - Cohesion. There is no air present in plant stems precisely because it prevents cohesion and therefore the movement of water molecules and minerals up the plant.

You're gonna fail biology my friend.

0:32 is bullshit, that's just underpressure building up, works with air too. No hydrogen bonds with air.
