Imagine you see a plant outside. It looks like it is just sitting there. But, if you use a special camera called a thermal camera, you will see something strange. The plant is colder than the air around it. This is weird because the sun is shining and the air is hot. You would think that the plant would get hot like everything else. So, what is going on?
This is because of something called photosynthesis. Plants use energy from the sun to make food. But, they don't use all of the energy for that. They also use some of it to make water evaporate. And that is what makes the plant cool. It's like the plant is sweating.
So, plants are not just sitting there. They are helping to keep the air cool. And that is good for the environment.
