Which of the following is not true for genetically modified plants

Options

A. Increased reliance on chemical pesticides
B. Helped to reduce post harvest losses
C. Enhanced nutritional value of food
D. Made crops more tolerent to abiotic stresses

Answer

To determine which statement is not true for genetically modified plants, we can analyze each statement based on the characteristics and benefits of genetically modified organisms (GMOs). Here’s a step-by-step breakdown of the solution:

### Step-by-Step Solution:

1. **Understand the Characteristics of Genetically Modified Plants**:
- Genetically modified plants are designed to possess certain traits that enhance their growth and resistance to various environmental factors.

2. **Identify the Benefits of GMOs**:
- **Tolerant to Abiotic Stress**: GMOs are engineered to withstand abiotic stresses such as drought, heat, cold, and salinity.
- **Reduced Reliance on Chemical Pesticides**: Many GMOs are modified to be resistant to pests, which decreases the need for chemical pesticides.
- **Reduced Post-Harvest Loss**: GMOs can be modified to have longer shelf lives and better resistance to spoilage, thus reducing post-harvest losses.
- **Enhanced Nutritional Value**: Some GMOs are designed to have improved nutritional profiles, such as increased vitamins or minerals.

3. **Analyze Each Statement**:
- **Statement A**: "Increased reliance on chemical pesticide."
- This is **not true** because GMOs typically reduce reliance on chemical pesticides.
- **Statement B**: "Help to reduce post-harvest losses."
- This is **true** as GMOs are designed to minimize losses after harvest.
- **Statement C**: "Enhance nutritional value of food."
- This is **true** as some GMOs are developed to have better nutritional content.
- **Statement D**: "Made crop more tolerant to abiotic stress."
- This is **true** as GMOs are often engineered for tolerance to abiotic stresses.

4. **Conclusion**:
- The statement that is not true regarding genetically modified plants is **Statement A**: "Increased reliance on chemical pesticide."

### Final Answer:
The answer is **Option A**: Increased reliance on chemical pesticide.
