A woody plant after the fall of all leaves exhibit

Options

A. Stomatal transpiration
B. Cuticular transpiration
C. Lenticular transpiraiton
D. 1 and 3

Answer

### Step-by-Step Solution:

1. **Understanding Transpiration**:
- Transpiration is the process by which plants lose water, primarily through small openings called stomata. It can occur through three main types: stomatal, cuticular, and lenticular transpiration.

2. **Types of Transpiration**:
- **Stomatal Transpiration**: This occurs through stomata, which are primarily found on the leaves. It accounts for about 90% of the total transpiration in plants.
- **Cuticular Transpiration**: This occurs through the cuticle, a waxy layer covering the leaves and stems. It is minimal, accounting for about 0.1% to 1% of total transpiration.
- **Lenticular Transpiration**: This occurs through lenticels, which are small openings in the bark of woody plants. Lenticels allow for gas exchange and can also facilitate water loss.

3. **Analyzing the Scenario**:
- The question specifies a "woody plant after the fall of all leaves." Since the leaves are gone, stomatal transpiration cannot occur because there are no stomata present.
- With the absence of leaves, cuticular transpiration is also minimal and not significant enough to be considered a major form of transpiration in this scenario.

4. **Identifying the Correct Type of Transpiration**:
- The only type of transpiration that can still occur in a woody plant without leaves is lenticular transpiration. This is because lenticels are present on the stems of woody plants and can facilitate water loss even when leaves are absent.

5. **Conclusion**:
- Therefore, the correct answer to the question is that a woody plant after the fall of all leaves exhibits lenticular transpiration.
