In tall trees water is absorted due to

Options

A. Transpiration/suction pull
B. Root Pressure
C. Caapillary action
D. Photosynthesis

Answer

To answer the question "In tall trees, water is absorbed due to," we need to analyze the options provided and understand the processes involved in water absorption in plants, especially in tall trees.

### Step-by-Step Solution:

1. **Understanding Photosynthesis**:
- Photosynthesis is the process by which plants convert light energy into chemical energy, producing glucose and oxygen from carbon dioxide and water. However, it does not directly relate to the absorption of water in tall trees.
- **Conclusion**: Photosynthesis is not the correct answer.

2. **Evaluating Capillary Action**:
- Capillary action refers to the ability of water to move through narrow spaces due to adhesive and cohesive forces. While it plays a role in the movement of water within small plants or soil, it is not the primary mechanism for water absorption in tall trees.
- **Conclusion**: Capillary action is not the correct answer.

3. **Considering Root Pressure**:
- Root pressure is generated when water from the soil is pushed into the roots and up into the plant. This pressure is more significant in smaller plants or during certain conditions but is not sufficient to explain how tall trees absorb water.
- **Conclusion**: Root pressure is not the correct answer for tall trees.

4. **Identifying Transpiration and Suction Pull**:
- Transpiration is the process of water vapor loss from the aerial parts of the plant, primarily through stomata. This loss creates a negative pressure (suction pull) in the xylem vessels, which helps draw water upward from the roots to the leaves.
- In tall trees, this transpiration pull is essential for moving water against gravity over long distances.
- **Conclusion**: The correct answer is transpiration or suction pull.

### Final Answer:
In tall trees, water is absorbed due to **transpiration or suction pull**.
