Detailed explanation-1: -In monocots, the primary root is short lived. It is replaced by a large number of roots which originate from the base of the stem. These roots constitute the fibrous root system.

Detailed explanation-2: -The monocotyledonous plants possess the adventitious or the fibrous type of root system. There are many fine thread-like branches which develop from any other part of the plant rather than the radicle. These type of roots do not grow much deeper but spread in the region widely to provide support the plant.

Detailed explanation-3: -The root system of monocots is thus wholly adventitious-i.e., the roots originate laterally from the stem or from the hypocotyl (the region of transition between the root and the stem in the embryo). The roots are all slender, and the plant is said to be fibrous-rooted.

Detailed explanation-4: -Monocots, including onions and grasses, have fibrous root systems.

Detailed explanation-5: -A fibrous root system is universal in monocotyledonous plants and ferns. The examples of plants with fibrous roots are maize, paddy, wheat, grass etc.
