Detailed explanation-1: -A system that has no dominant primary root but is made of many primary and secondary roots of similar size is called a fibrous root system . Monocot plants typically have fibrous root systems.

Detailed explanation-2: -Fibrous root systems have many small branching roots, called fibrous roots, but no large primary root. The huge number of threadlike roots increases the surface area for absorption of water and minerals, but fibrous roots anchor the plant less securely.

Detailed explanation-3: -Root Systems Taproot systems feature a single, thick primary root, called the taproot, with smaller secondary roots growing out from the sides. The taproot may penetrate as many as 60 meters (almost 200 feet) below the ground surface.

Detailed explanation-4: -Primary and secondary roots are present in fibrous root system.

Detailed explanation-5: -Taproot consists of the one, long main root, where secondary, tertiary and rootlets are visible. Even the primary root is very thick as compared to other roots (Carrot, Radish). Whereas fibrous oradventitious roots contains short-lived roots, which are shallow and the growth can be either underground or aerial.
