The root is a very important part of the plant: thanks to it, it can remain well attached to the ground, feed itself and, therefore, also grow . It is an organ that is normally underground, that is, it is below ground level; however, there are those that are aerial and aquatic.
Knowing the parts of the root of a plant is very interesting , as it will help you to know more about the magnificent plant kingdom.

What is the root?
The root is an organ that grows in the opposite direction to the stem , which is what is known as positive geotropism.
According to its structure:
- Axonomorphic : they are those that are formed by a thick main root and others that come out of the main, thinner one.
- Fasciculated : they are those that do not have a main root.
- Napiformes : they are those that have a main root that accumulates reserve substances, so that it thickens much more than the rest.
- Tuberous : they are roots that resemble the fasciculate ones, but in all of them they accumulate reserve substances so they experience a thickening.
- Branched – do not have a main root. They are quite similar to the branches of a tree.
Depending on your location:
- Adventitious : they are those that some plants develop to be able to spread or climb.
- Aquatic : are those that live in water.
- Suckers : they are the ones that get inside another plant to absorb its sap.
What are its parts?
Although not all roots have all these parts, in general we will find:
- Neck : it is the part that is located just at ground level.
- Branching zone : it is the part where the secondary roots begin to form.
- Piliferous area or absorbent hairs : it is covered with hairs that are responsible for absorbing water and mineral salts from the soil.
- Zone of growth or cell division : it is the zone where root growth takes place.
- Cap : it is a cap that protects the tip of the root so that it is not damaged as it is introduced into the interior of the soil.
