Plants have three types of root systems:

(i) Taproot - This system has a main taproot that is larger and grows faster than the branch.

(ii) Fibrous- Fibrous root system has all roots of the same size, the whole root system is fibrous and branches grow in all directions. They are mostly found in monocots. The main function of the fibrous root is to anchor the plant.
