Question:

Select the correct statements with regard to genetically modified crop:

A. Made crops less resistant to abiotic stresses
B. Reduce reliance on chemical pesticides
C. Help to reduce post harvest loss
D. Help to depreciate nutritional value of food

Choose the correct answer from the options given below:

Options:

B and C only

A and D only

B, C and D only

A and C only

Correct Answer:

B and C only

Explanation:

The correct answer is Option (1) -B and C only

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., golden rice, i.e., Vitamin ‘A’ enriched rice
