Which of the following best describes the main purpose of developing Genetically Modified Organisms (GMOs) in agriculture ?
Show answer & explanation
Correct answer: B
Explanation
Answer: To improve crop yield, pest resistance, and nutritional quality
Explanation: Genetically Modified Organisms (GMOs) in agriculture are developed by altering the genetic makeup of crops to introduce desirable traits. The primary goal is to increase productivity (higher yield), enhance resistance to pests and diseases, and improve nutritional value (e.g., vitamin-enriched crops). This helps ensure food security and reduces crop losses.
Additional Key Facts:
GM crops can be engineered for herbicide tolerance and drought resistance.
Example: Bt cotton in India is resistant to bollworm pests.
Golden Rice is enriched with Vitamin A.
GM technology uses genetic engineering techniques.
There are debates regarding biosafety, environmental impact, and regulation.
Potential Exam-Oriented Questions & Answers:
Question: What does “Bt” in Bt cotton stand for?
Answer: Bacillus thuringiensis (a bacterium used for pest resistance).
Question: What is Golden Rice known for?
Answer: High Vitamin A content.
