How do plants release water?

Hello everyone! How are you getting through the heat wave? Surely you have increased your fluid intake, right? And it is that the human body, being exposed to such high temperatures, expels water at a higher speed through the pores of the skin. That way, when the wind passes, he manages to stay cool, or at least he tries to. This process is known as transpiration , and it is something that also occurs in plant beings.

If you’re curious about how plants expel water , read on to find out more about this incredible phenomenon.

To get water, we get a bottle or a glass, but the plants absorb it through their roots . The root system can extend horizontally, staying very close to the surface, or drill down into the ground depending on where the moisture is. Once they have found water, the water is immediately sent to the stems and leaves in order to carry out photosynthesis and ensure the proper growth of the plant. All thanks to the xylem and the phloem .

But of course, what function do these strangely named parts have? It is much simpler than it seems. The xylem is a woody tissue found inside the stem, and is responsible for transporting water, mineral salts and other essential nutrients upwards to all parts of the plant; the phloem, on the other hand, transports the elaborated sap , which is composed of organic and inorganic nutrients produced by the photosynthetic parts -that is, those parts of the plant beings where there is a presence of chlorophyll- downwards towards the roots.


To live you have to breathe, and in the process it is inevitable to lose water. Plants “eliminate” all that they do not need in the form of water vapor, expelling it through the pores (or stomata), located on the underside of the leaves, as they open.

Do the following experiment with your family to make sure your plant breathes: Wrap the leaves in a clear plastic bag . You will see that, after a short period of time, there are droplets of water inside, an unequivocal sign that it is alive, and therefore breathes.
