The phenomenon of absorption of water that depends on water loss from aerial parts of plant (Transpiration) is

Options

A. Active absorption
B. Passive absorption
C. Both passive and active absorption
D. None of the above

Answer

To solve the question regarding the phenomenon of absorption of water that depends on water loss from the aerial parts of the plant (transpiration), we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Transpiration**:
- Transpiration is the process by which water vapor is lost from the aerial parts of the plant, primarily through small openings called stomata on the leaves. This loss of water creates a negative pressure within the plant.

2. **Role of Transpiration in Water Absorption**:
- As water evaporates from the leaves, it creates a suction effect (transpirational pull) that helps draw water up from the roots through the xylem vessels. This process is crucial for the upward movement of water.

3. **Types of Water Absorption**:
- There are two main types of water absorption in plants: active absorption and passive absorption.
- **Active Absorption**: This process requires energy (ATP) to move water against its concentration gradient, usually involving root hairs actively taking up minerals and water.
- **Passive Absorption**: This process does not require energy. Water moves from an area of higher concentration in the soil to an area of lower concentration in the roots due to the negative pressure created by transpiration.

4. **Identifying the Correct Type**:
- Since the question specifically mentions that the absorption of water depends on water loss from the aerial parts of the plant (transpiration), this indicates that the process is driven by the negative pressure created by transpiration.
- Therefore, the absorption of water in this context is classified as **passive absorption**.

5. **Conclusion**:
- Based on the explanation, the correct answer to the question is **passive absorption**.

### Final Answer:
The phenomenon of absorption of water that depends on water loss from aerial parts of the plant (transpiration) is **passive absorption**.
