Worked practice questions

In MONOCOT plants, the primary root is short-lived and is replaced by:

  1. Pneumatophores
  2. Adventitious roots only
  3. Tap root system
  4. Fibrous root system (arising from the base of the stem; e.g. wheat)
Show answer and solution

Correct answer: D. Fibrous root system (arising from the base of the stem; e.g. wheat)

**Monocots have a fibrous root system:** many roots of similar size arising from the base of the stem after the primary root dies early. Wheat is a classic example. Dicots (e.g. mustard) have a tap root system.

The arrangement of leaves on the stem (alternate/opposite/whorled) is called:

  1. Vernation
  2. Aestivation
  3. Phyllotaxy
  4. Venation
Show answer and solution

Correct answer: C. Phyllotaxy

Phyllotaxy = leaf arrangement on stem/branch. **Three types:** alternate (china rose, mustard), opposite (Calotropis, guava), whorled (Alstonia, more than two leaves per node). Venation is vein arrangement aestivation is petal/sepal arrangement in bud.

Reticulate venation is generally characteristic of:

  1. Dicots (network of veins; in monocots veins run parallel)
  2. Pteridophytes
  3. Monocots
  4. Gymnosperms
Show answer and solution

Correct answer: A. Dicots (network of veins; in monocots veins run parallel)

Dicotyledons typically have reticulate venation (network pattern). Monocotyledons typically have parallel venation (veins running parallel along the leaf). This is one of the classic dicot-vs-monocot distinctions.
