TYPES OF ROOTS

 

Taproot

Fibrous root

Elongated taproots

Tuberoid root

Branched

Taproot, It is the primary root from which secondary roots ( rootlets) derive from.

Fibrous roots do not have a primary root. They show almost the same size and width.

Elongated taproots offer a very fat primary root because they accumulate food it.

Tuberoid roots are fibrous roots that became fat because of the accumulation of nutrients.

Branched roots do not have a primary root. They resemble to the branches of a tree.

OTHER TYPES OF ROOTS

Besides the more usual roots named above, we should consider those ones that are a bit special. Those not inserted into the soil, either because they are in the open air or because they live inside the water. These special roots are the following:

Adventitious roots

Those who grow from a stem and are used by some plants to spread along the surface of the soil.

Water roots

Those living in the water.

Parasite roots

They are stuck on another plant , sucking the nutrients from it.The mistletoe is a clear example of this type.
