During passive absorption, water is absorbed as a result of tension created by ……………….

Explanation

**Step-by-Step Text Solution:**

1. **Understanding Passive Absorption**: Passive absorption refers to the process by which plants take up water without the expenditure of energy. This process relies on physical forces rather than metabolic energy.

2. **Role of Transpiration**: Transpiration is the process through which water vapor is lost from the aerial parts of the plant, primarily through small openings called stomata. This loss of water creates a negative pressure or tension in the leaf.

3. **Creation of Tension**: As water evaporates from the stomata during transpiration, it creates a tension in the water column present in the xylem vessels. This tension pulls water upward from the roots through the xylem.
