Detailed explanation-1: -Monocot roots are fibrous, meaning they form a wide network of thin roots that originate from the stem and stay close to the surface of the soil. In contrast, dicots have “taproots, ” meaning they form a single thick root that grows deep into the soil and has smaller, lateral branches.

Detailed explanation-2: -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-3: -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-4: -Thin, branched roots that arise from the base of the stem are known as fibrous roots. Grasses and monocotyledons are characterised by the presence of fibrous roots.
