Which of the following statement is true/false regarding the genetic modification of crops?

Options

A. made crops less sensitive to abiotic stresses
B. increased reliance on chemical pesticides
C. helped to reduce post harvest losses
D. decreased efficiency of mineral usage by plants

Answer

To determine which statements regarding the genetic modification of crops are true or false, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement 1: "Made crops less sensitive to abiotic stresses."**
- **Analysis:** Genetic modification has indeed enabled crops to become more tolerant to various abiotic stresses such as drought, salinity, and temperature extremes. This means that crops can survive and thrive in conditions that would typically be detrimental to their growth.
- **Conclusion:** This statement is **True**.

2. **Statement 2: "Increased reliance on chemical pesticides helps to reduce post-harvest losses."**
- **Analysis:** Genetic modification has led to the development of pest-resistant crops, which reduces the need for chemical pesticides. This means that farmers can rely less on chemical treatments, not more. Therefore, this statement is misleading.
- **Conclusion:** This statement is **False**.

3. **Statement 3: "Helps to reduce post-harvest losses."**
- **Analysis:** Genetic modification can enhance the shelf-life and resilience of crops, which indeed helps to reduce post-harvest losses. By making crops more resistant to spoilage and damage, the overall yield that reaches consumers is increased.
- **Conclusion:** This statement is **True**.

4. **Statement 4: "Decreased efficiency of mineral usage by plants."**
- **Analysis:** Genetic modification has been shown to improve the efficiency of mineral uptake in plants. This means that plants can utilize nutrients more effectively, which helps maintain soil fertility and enhances the nutritional value of the crops.
- **Conclusion:** This statement is **False**.

### Summary of Statements:
- Statement 1: **True**
- Statement 2: **False**
- Statement 3: **True**
- Statement 4: **False**
