Which of the following statements regarding Genetically Modified Organisms are not correct?
(A) Crops are more tolerant to abiotic stresses
(B) Pest-resistant crops
(C) Post harvest losses are more
(D) Reduced efficiency of mineral usage by plants
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (C) and (D) only
(A) Crops are more tolerant to abiotic stresses — True. GM crops can tolerate cold, drought, salt and heat.
(B) Pest-resistant crops — True. Bt crops reduce the use of chemical pesticides.
(C) Post harvest losses are more — False. GM crops help to reduce post-harvest losses.
(D) Reduced efficiency of mineral usage by plants — False. GM plants use minerals more efficiently, which prevents early exhaustion of soil fertility.
NCERT Extract:
Biotechnological Applications in Agriculture – “… Genetic modification has: (i) made crops more tolerant to abiotic stresses (cold, drought, salt, heat). (ii) reduced reliance on chemical pesticides (pest-resistant crops). (iii) helped to reduce post harvest losses. (iv) increased efficiency of mineral usage by plants (this prevents early exhaustion of fertility of soil).”
