Options

A. 5 percent
B. 10 percent
C. 15 percent
D. 50 percent

Answer

To solve the question regarding how mineral toxicity can reduce the dry weight of tissues, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Mineral Toxicity**:
- Mineral toxicity occurs when there is an excess of essential minerals in plants, surpassing the critical concentration necessary for their growth and survival.

2. **Identifying Essential Minerals**:
- Plants require 17 essential minerals for their proper growth and development. Each mineral has a specific critical concentration that must be maintained.

3. **Effects of Mineral Toxicity**:
- When the concentration of any essential mineral exceeds its critical level, it leads to toxicity. This can adversely affect the plant's health and growth.

4. **Impact on Dry Weight**:
- According to the information provided, mineral toxicity can lead to a reduction in the dry weight of plant tissues. The specific reduction mentioned is 10%.

5. **Conclusion**:
- Based on the information, we conclude that mineral toxicity can indeed reduce the dry weight of tissues by 10%. Therefore, the correct option is option 2 (10%).

### Final Answer:
Mineral toxicity can reduce the dry weight of tissues by **10%**.
