Q179 / 180 · AIIMS 2019 (25 May) · Zoology

-Assertion : Biofortification is used to increase nutrient value of crops. Reason : Meristem culture is used to obtain virus resistant plants.

  • A
    If both assertion and reason are true and reason is the correct explanation of assertion.
  • Correct answer
    B
    If both assertion and reason are true but reason is not the correct explanation of assertion.
  • C
    If assertion is true but reason is false.
  • D
    If both assertion and reason are false.

Solution

Breeding of crops with higher levels of vitamins and minerals or higher protein and healthier fats is called biofortification. Meristem is a localised group of cells, which are actively dividing and undifferentiated but ultimately giving rise to permanent tissue. Even though the plant is infected with virus, the meristem remains free of virus.

Hence, the correct answer is option: 'B'.
