A Level Biology Revision "Transpiration and the Cohesion-Tension Theory"

You can find all my A Level Biology videos fully indexed at www.freesciencelessons.co.uk/...
In this video, we look at transpiration and the cohesion-tension theory of water movement. First we explore what is meant by transpiration. We then explore how transpiration takes place, looking at cohesion, adhesion, capillary action and the cohesion-tension theory.

Thank you so much for summarizing topics that would take me hours to study and single handedly saving my A levels 😆

this is great thank you

[@quarantinedgoose5396]

thanks for the video I'm doing my AS biology test today and you've helped me a lot with preparation. Thanks

[@malikmustafa5398]

a very good video but the pronunciation of cohesion and adhesion is hilarious

It's very close to the normal pronounciation of it bar the fact that he has a regional accent? 😂😂😂
