Understanding Water - Chapter 03:

What is molecular adhesion?

In this third chapter of a multi-part documentary series, we explore water adhesion, focusing on its role in transpiration and capillary action in plants. Adhesion is one of the key properties of water that allows plants to transport water (and nutrients) from their roots all the way up to the leaves.

So how can water travel upwards, defying gravity?

Learn how capillary action and water's molecular properties work together to defy gravity. This video explains how this is possible, as well as the importance of water's role in the transpiration process, and plant physiology.
