Question:

Genetic modification has led to which of the following outcomes.Which of the statements given below are correct?

I. Genetic modification has decreased the dependence on chemical pesticides.

II. Genetic modification has minimized post-harvest losses.

III. Genetic modification has improved the plants' efficiency in utilizing minerals.

IV. Genetic modification has increased the nutritional value of the food.

 

Options:

 II, III and IV

III and IV

I, II and III

I, II, III and IV

Correct Answer:

I, II, III and IV

Explanation:

Genetically Modified Organisms (GMOs) refer to plants, bacteria, fungi, and animals whose genes have been altered through manipulation. GM plants have proved to be beneficial in various ways, as follows:

(i) GM technology has made crops more resilient to abiotic stresses, such as cold, drought, salt, and heat, enabling them to thrive in challenging environmental conditions.

(ii) Genetic modification has decreased the reliance on chemical pesticides by creating pest-resistant crops, which reduces the need for harmful chemical inputs and promotes sustainable agriculture.

(iii) GM has contributed to reducing post-harvest losses, enhancing the shelf life of crops, and ensuring better food security.

(iv) The efficiency of mineral usage by plants has been improved through genetic modification, preventing early soil fertility exhaustion and promoting sustainable agricultural practices.

(v) Genetic modification has been utilized to enhance the nutritional value of food, with examples like golden rice, enriched with Vitamin 'A', providing essential nutrients to combat malnutrition.

Furthermore, GM technology has enabled the creation of tailor-made plants, serving as alternative resources for industries, producing starches, fuels, pharmaceuticals, and other valuable products.

In summary, genetic modification has revolutionized agriculture and various industries, offering solutions to global challenges and providing opportunities to enhance food security, nutrition, and sustainable resource utilization.
