Root parts of a plant

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.

Types

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.
