Transpiration has more than one purpose, it

Options

A. Supplies water for photosynthesis
B. Transports minerals
C. Maintains the shape of the plants by keeping cells turgid
D. All of these

Answer

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

1. **Understanding Transpiration**: Transpiration is the process through which water vapor is lost from the aerial parts of the plant, primarily through small openings called stomata located on the leaves.

2. **Purpose of Transpiration**:
- **Water Supply for Photosynthesis**: Transpiration helps in supplying water to the leaves, which is essential for the process of photosynthesis. During photosynthesis, carbon dioxide and water react to produce glucose and oxygen.
- **Transport of Minerals**: As water is absorbed by the roots from the soil, it carries dissolved minerals along with it. Transpiration creates a negative pressure (transpiration pull) that aids in the upward movement of this water and minerals through the xylem to various parts of the plant.
- **Maintaining Turgidity**: Transpiration helps maintain turgor pressure in plant cells. Turgidity is crucial for maintaining the structure and shape of the plant, preventing wilting and ensuring that the plant remains upright.

3. **Conclusion**: Since transpiration serves multiple purposes, including supplying water for photosynthesis, transporting minerals, and maintaining the shape of the plant by keeping cells turgid, the correct answer to the question is "all of these."

4. **Final Answer**: The correct option is "all of these."
