Worked practice questions

A tap root system is characteristic of

  1. Most monocotyledonous plants like wheat
  2. Most pteridophytes like ferns and horsetails
  3. Most gymnosperms like Cycas and Pinus
  4. Most dicotyledonous plants like mustard
Show answer and solution

Correct answer: D. Most dicotyledonous plants like mustard

**Tap root system:** primary root persists and forms lateral branches (dicots). Monocots have fibrous root systems where the primary root is short-lived and is replaced by adventitious roots from the stem base.

In wheat plants, the root system is

  1. Tap root system from primary radicle
  2. Fibrous root system from stem base
  3. Pneumatophore system for gas exchange
  4. Mycorrhizal system without true roots
Show answer and solution

Correct answer: B. Fibrous root system from stem base

Wheat (monocot) has a fibrous root system: the primary root is short-lived and many adventitious roots arise from the stem base. Pneumatophores are seen in mangroves mycorrhiza is a fungal association.

Adventitious roots arise from

  1. The tip of an axillary leaf bud only
  2. The apex of a flowering inflorescence
  3. The radicle of the developing embryo
  4. Parts of the plant other than radicle
Show answer and solution

Correct answer: D. Parts of the plant other than radicle

Adventitious roots originate from any plant part other than the radicle (e.g., stem in grass, banyan, Monstera). Tap and fibrous roots both ultimately trace to the radicle.
