In preparing for NEET, a sound understanding of various biological topics is crucial. One such topic under NEET Biology is Strategies for Enhancement of Food Production, which delves into the methods and technologies used to improve food yield and quality to meet the rising demand. Here we provide a compilation of 25 MCQs to help you gauge your understanding and prepare better for the upcoming exams.
1. Which among the following is a conventional method of crop improvement?
Answer:
Explanation:
Hybridization is a traditional method of cross-breeding between genetically dissimilar plants to produce hybrids that possess desirable characteristics.
2. Which of the following organisms is used in biofortification?
Answer:
Explanation:
Biofortification is the process of increasing nutritional value of food crops through agronomy, breeding, or biotechnology. The listed organisms are not used in biofortification.
3. Which of the following is not a method of crop improvement?
Answer:
Explanation:
All listed options are methods used in crop improvement to enhance productivity and crop quality.
4. Which of the following is a method of in-situ conservation?
Answer:
Explanation:
In-situ conservation involves preserving species in their natural habitats like wildlife sanctuaries, whereas ex-situ conservation includes methods like botanical gardens, gene banks, and seed banks.
5. What is the purpose of Green Revolution?
Answer:
Explanation:
The Green Revolution refers to a series of research, development, and technology transfer initiatives, during the late 1960s and 1970s, that increased agriculture production worldwide, particularly in the developing world.
6. What is the goal of plant breeding?
Answer:
Explanation:
Plant breeding aims at creating new plant varieties, improving existing plant species, and enhancing desirable traits such as yield, nutritional quality, and resistance to diseases.
7. Which of the following is a method of ex-situ conservation?
Answer:
Explanation:
Ex-situ conservation involves preserving biological diversity outside natural habitats. Gene banks are a form of ex-situ conservation where genetic material is stored.
8. The process of improving nutritional quality of food crops is known as?
Answer:
Explanation:
Biofortification is the process of improving the nutritional quality of food crops through agronomy, breeding, or biotechnological methods.
9. Which of the following is a feature of genetically modified crops?
Answer:
Explanation:
Genetically modified crops have been engineered for increased nutritional value, higher resistance to pests and diseases, and better yield.
10. Which among the following is a concern related to genetically modified crops?
Answer:
Explanation:
Concerns related to genetically modified crops include potential allergenicity and the risk of gene transfer to non-target species which may cause ecological imbalances.
