Question

Which of the following statements is not true about GM crops?

• A. Enhanced nutritional value
• B. GM crops are more susceptible to pests and abiotic stress
• C. Increased efficiency of mineral usage by plants
• D. GM crops helps in reducing post harvest loss

Answer 1

The correct option is B GM crops are more susceptible to pests and abiotic stress

Organisms whose genes have been modified and combined with the genes of other organisms using recombinant DNA technology are known as genetically modified organisms.
Genetic modification in plants have potential benefits and some of them are listed as follows:
1. Enhanced nutritional value of certain crops, for example, Golden Rice is richly fortified with ꞵ - carotene (precursor of vitamin A)
2. GM (genetically modified) crops are more resistant to pests and abiotic stress like drought, heat, etc.
3. Increased efficiency of mineral uptake in plants thereby preventing early exhaustion of soil fertility
4. Increased shelf life of certain fruits and vegetables such that they remain fresh for a longer duration or mature slowly. This helps to prevent the post-harvest loss of crops due to ripening or rotting.
