Transpiration

[thekeyring]

how am I here. I don't study science.

[RavenMischke]

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

[dakingisgman]

@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.

[RavenMischke]

@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]

@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. :)

Excellent help. Thank you.

[sbelo11]

thank youu!

[safaanej]

thank you, this is really helpful :)

[lazlow6661]

this is reallllly helpful thank you



[ekansh786]

i hate science i also hate transpiration

[lameisforlosers]

@ekansh786 Yo dog, don't hate science. How else would we have cool things like 3D printing and the Crab Nebula? Science is so relevant.

Very helpful!

thank you for this video

[ScorpiaX]

Thank you. Much easier to understand than a bunch of technical terms in text.

[cloverhannah]

good presentation~ thanks!!

[okies90]

easier to understand then my textbook lol

thnx :D

[waniey6690]

thank you..

ur explanation is same with my text book..

now i understand the transpiration from the root to the leaves...

[94jmcorrea]

thank you very clear explanation
