Genetic modification has:
(A) Made crops more tolerant to abiotic stresses
(B) Reduced reliance on chemical pesticides
(C) Increased efficiency of mineral usage by plants
(D) Enhanced nutritional value of food
Choose the correct answer in following options:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (A), (B), (C) and (D)
Plants, bacteria, fungi and animals whose genes have been changed by manipulation are called Genetically Modified Organisms (GMO). GM plants have been useful in many ways.
(A) Made crops more tolerant to abiotic stresses — Correct. GM crops can stand cold, drought, salt and heat better.
(B) Reduced reliance on chemical pesticides — Correct. Pest-resistant crops, such as Bt cotton, need less chemical pesticide.
(C) Increased efficiency of mineral usage by plants — Correct. This prevents the early exhaustion of the fertility of the soil.
(D) Enhanced nutritional value of food — Correct. Golden rice, which is rich in vitamin A, is an example.
