The loss of water through cuticle reaches upto

Options

A. `5%`
B. `10%`
C. `20%`
D. `40%`

Explanation

To answer the question regarding the loss of water through the cuticle, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Cuticle Function**: The cuticle is a waxy layer that covers the surface of leaves and stems in plants. Its primary function is to reduce water loss by providing a barrier to evaporation.

2. **Identifying Water Loss Through Cuticle**: Research indicates that the loss of water through the cuticle typically accounts for a small percentage of the total water loss in plants.

3. **Comparing Water Loss Percentages**:
- Water loss through the cuticle is generally estimated to be between 5% to 10% of the total water loss.
- In contrast, the majority of water loss occurs through stomata, which can account for about 90% or more of total water loss.

4. **Selecting the Correct Option**: Given the options provided (5 percent, 10 percent, 20 percent, 40 percent), the most accurate representation of the water loss through the cuticle falls within the range of 5% to 10%. Since the question asks for the maximum value, we select 10 percent.

5. **Conclusion**: Therefore, the loss of water through the cuticle reaches up to **10 percent**.

### Final Answer:
The loss of water through the cuticle reaches up to **10 percent**.
