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: -Dicot plants have tap root system and fibrous root system is seen in monocots. Taproots have a main central root upon which, small, lateral roots called root hairs are attached.

Detailed explanation-3: -Monocot plants such as lilies, orchids, palms, irises, and grasses are supplied with an extensive fibrous root system. Although a primary root initially emerges from a seedling, it remains just long enough to establish a foothold and is quickly replaced by the outgrowth of many slender roots.

Detailed explanation-4: -Dicots have a tap root system, while monocots have a fibrous root system. A tap root system has a main root that grows down vertically, and from which many smaller lateral roots arise.

Detailed explanation-5: -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.
