How plants drink water: part 7️⃣

Adhesion: liquids stick to the surface of their container.  🤮 

(To be fair, the vomit emoji was the only one with any sticky substance. 😉)

Imagine you’re at the beach on a hot day, and you take a sip on the straw of your lemonade. After you’re done, you notice that there’s some lemonade that’s still sticking to the inside of your straw.

It’s sticking because the lemonade molecules, which are largely water, stick together. The straw, on the other hand, has a large surface area. That means the lemonade can find many places inside the straw to cling to. Just like the lemonade sticks to the inside of the straw, water will stick to the inside of the xylem. That’s the force of adhesion in a nutshell.

So how do all these forces work together? Read about it here.
