Major loss of water in transpiration occurs through

Options

A. Cuticle
B. Bark
C. Hydathodes
D. Stomata

Answer

To answer the question "Major loss of water in transpiration occurs through," we will analyze the types of transpiration and identify where the majority of water loss occurs.

### Step-by-Step Solution:

1. **Understand Transpiration**: Transpiration is the process by which water is lost from the plant to the atmosphere. This primarily occurs through various structures in the plant.

2. **Identify Types of Transpiration**: There are three main types of transpiration:
- **Stomatal Transpiration**: Water loss through stomata (tiny openings on leaves).
- **Cuticular Transpiration**: Water loss through the cuticle (the waxy layer on leaves).
- **Lenticular Transpiration**: Water loss through lenticels (small openings in the bark).

3. **Determine the Major Pathway**:
- According to the information, stomatal transpiration accounts for **50-90%** of total transpiration.
- Cuticular transpiration accounts for **9-9.9%**.
- Lenticular transpiration accounts for only **0.1-1%**.

4. **Conclusion**: Since stomatal transpiration is responsible for the majority of water loss in plants, we conclude that the major loss of water in transpiration occurs through **stomata**.

### Final Answer:
The major loss of water in transpiration occurs through **stomata**.
