Why do plants follow the light?

If you are one of those who likes to walk through the fields and observe the plants, it is very likely that you have noticed how some plants like lthe sunflowers, they are always looking towards the sun, in search of the light and its rays. Although they cannot move from the ground, during the day they move their stem according to where the great star king is.

In addition to sunflowers, you have surely noticed that some plants grow in the same direction from which the sun rises, and during the day they try to follow the light that comes from this great star. But have you ever wondered why some plants follow the path of the sun? Although the answer may seem simple, it is not at all. One of the first people to ask this was Leonardo Da Vinci, and from this question, many more people began to ask the same.

Currently, a group of European researchers have made discoveries that bring us a little closer to the answer: apparently plants have a plant hormone called auxin, which makes them seek sunlight. This hormone is stored in certain places in the plant, such as the growing sections of the plant, and is then transported to other places, including the stem.

So that the plant can reach absorb the sun's rays adequately and optimallyIt is very important that the stem is straightened as soon as possible so that it can reach its maximum height and catch the sun's rays. It is for this reason that greater amounts of this auxin hormone are supplied to the lower area of ​​the plant, which is why the stem begins to grow straight. In this way, plants are able to take better advantage of the changing conditions of their environmental environment.
