DENDROLOGY

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: -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-3: -Fibrous roots are the roots formed by thin, moderately branching roots emerging from the stem. Wheat, rice and corn are some of the examples of fibrous roots.
