Which of the following is not a useful effect of GM plants?                               

(i)Made crops more tolerant to abiotic stresses like cold, drought, salt, heat.
(ii)Reduced reliance on chemical pesticides by producing pest-resistant crops.
(iii)Decrease efficiency of mineral usage by plants.
(iv)Enhanced nutritional value of food, e.g., Vitamin ‘A’ enriched rice.
(v)Create tailor-made plants to supply alternative resources to industries, in the form of starches, fuels and pharmaceuticals.

Plants, bacteria, fungi and animals whose genes have been altered by manipulation are called Genetically Modified Organisms (GMO). GM plants have been useful in many ways. 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). 
(v) enhanced nutritional value of food, e.g., Vitamin ‘A’ enriched rice.
