Question

Genetically modified organisms are used for

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

Answer 1

Answer: (D)

Genetic modification has:
$a$. Reduced reliance on chemical pesticides (pest-resist ant crops)
$b$. Made crops more tolerant to abiotic stresses (cold drought, salt, heat)
$c$. Enhanced nutritional value of food, e.g. vitamin ‘A’ enriched rice.
$d$. Increased efficiency of mineral usage by plants (this prevents early exhaustion of fertility of soil).
$e$. Helped to reduce postharvest losses.
$f$. In addition to these uses, GM has been used to create tailor -made plants to supply alternative resources to industries, in the form of starches, fuels and pharmaceuticals
