Genetically modified organisms have been useful in many ways. Which one of the following statements is not correct in the case of GMO plants?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → GMO plants rely on chemical pesticides.
GMO stands for Genetically Modified Organisms: plants, bacteria, fungi and animals whose genes have been altered by manipulation. All four options are about GMO plants.
Option (1) GMO plants are more tolerant to abiotic stresses. — A correct statement. Abiotic stresses are non-living factors such as cold, drought, salt and heat. Genetic modification has made crops bear them better.
Option (2) GMO plants rely on chemical pesticides. — Not a correct statement. A pest-resistant GM crop, such as Bt cotton, makes its own toxin against the pest. So it needs fewer sprays. GM plants have reduced the reliance on chemical pesticides; they do not rely on them.
Option (3) GMO plants reduce post harvest losses. — A correct statement. Post-harvest losses are the losses of a crop after it is picked, such as during storage. GM crops have helped reduce these losses.
Option (4) GMO plants enhance nutritional value of food. — A correct statement. Golden rice is an example. It is rich in Vitamin A, which ordinary rice lacks.
