Question

Roots developed from parts of the plant other than the radicle are called

• A. Tap roots
• B. Adventitious roots
• C. Nodular roots
• D. Fibrous roots

Answer 1

The correct option is B Adventitious roots

In plants, the shoots develop from the plumule and roots develop from the radicle. In majority of the dicotyledonous plants, the direct elongation of the radicle leads to the formation of primary root which grows inside the soil. It bears lateral roots of several orders that are referred to as secondary, tertiary, etc. roots. The primary roots and its branches constitute the tap root system. In some plants, like grass, Monstera and the banyan tree, roots arise from parts of the plant other than the radicle and are called adventitious roots.
