Transpiration facilitates

Options

A. Electrolyte balance
B. Absorption of water by roots
C. Opening of stomata
D. Excration of minerals

Answer

**Step-by-Step Solution:**

1. **Understanding Transpiration**: Transpiration is the process through which water vapor is lost from the plant, primarily through small openings called stomata, which are mainly found on the leaves.

2. **Location of Transpiration**: While transpiration can occur through various parts of the plant, the majority of water loss happens through the leaves due to a higher concentration of stomata.

3. **Role of Transpiration in Water Absorption**: Transpiration plays a crucial role in facilitating the absorption of water by the roots. As water evaporates from the leaves, it creates a negative pressure within the plant.

4. **Transpiration Pull Theory**: This negative pressure generated by transpiration pulls water upward from the roots through the xylem vessels. The more water that is lost through transpiration, the greater the negative pressure, and consequently, the more water is absorbed by the roots.

5. **Conclusion**: Therefore, the correct answer to the question "Transpiration facilitates" is the absorption of water by the roots.

**Final Answer**: Transpiration facilitates the absorption of water by the roots.
