Answer 2

While an adventitious root is one that originates from any portion of the plant other than the radicle or its descendants, a taproot is a primary root that lasts throughout the life of a plant.

Fibrous roots:

• The opposite of a taproot system is a fibrous root system.
• Typically, it develops from the stem as a series of thin, modestly branched roots.
• In ferns and monocotyledonous plants, a fibrous root system is present in all cases.
• When the tree is fully grown, the fibrous root systems resemble a carpet made of roots.
• Thin, somewhat branched roots that emerge from the stem to form fibrous roots.
• Examples of fibrous roots include wheat, rice, and corn.

Adventitious roots:

• Adventitious roots, which are formed both during normal development (crown roots on cereals and nodal roots on strawberries) and in reaction to stressful circumstances like flooding, nutrient scarcity, and wounding, are defined as plant roots that form from any non-root tissue.
• Ivy stems, horsetail rhizomes that grow quickly, ivy roots, and aspen tree roots that connect groves are a few examples of adventitious root systems.
• Such root development primarily serves to assist in oxygen delivery to the plant.
