Question

Genetically modified organisms are used for

• A. All of the above
• B. Reducing reliance on chemical pesticides
• C. Developing pest-resistant crops
• D. Increasing efficiency of mineral usage by plants that prevents early exhaustion of fertility of soil

Answer 1

The correct option is A All of the above

GMO (genetically modified organisms) can be defined as the organisms which have their genetic material altered for the expression of a particular trait.

Common aims to develop GMOs include the following:

• Resistance to pests
• Tolerant of abiotic stresses
• Improved nutritional value
• Reduction in:
  • Post harvest losses
  • Requirement for chemical pesticides etc.

Certain genetic modifications in crops make them less dependent on pesticide and insecticides. This is because they are genetically resistant to pests. Examples include Bt cotton, Bt corn etc.

Plants that can efficiently use the mineral nutrients can be developed by means of genetic engineering to prevent the exhaustion of fertility of the soil. This enhances the yield of the crops which can meet the increasing demand of the population.

Hence the correct option is
d. All of the above
