Water is mainly transported to shoot tips by the help of

Options

A. Capillarity
B. Root pressure
C. Transpiration pull
D. Canopy structure

Answer

**Step-by-Step Solution:**

1. **Understanding Water Transport in Plants**: Water is essential for plant growth and is primarily transported from the roots to the shoot tips. This process involves various mechanisms.

2. **Identifying the Mechanisms**: The options provided are capillary action, root pressure, transpirational pull, and canopy structure. We need to determine which of these is primarily responsible for transporting water to the shoot tips.

3. **Role of Transpiration**: Transpiration is the process where water evaporates from the leaves through small openings called stomata. This evaporation creates a negative pressure (suction) in the leaf area.

4. **Creating Suction Pressure**: As water evaporates from the leaves, it creates a suction effect that pulls more water upward from the roots through the xylem vessels. This phenomenon is known as transpirational pull.

5. **Absorption from Roots**: While transpiration occurs at the leaves, water is simultaneously absorbed from the soil by the roots. This combination of evaporation from the leaves and absorption from the roots creates a continuous flow of water upward.

6. **Conclusion**: The primary mechanism that facilitates the transport of water to the shoot tips is the transpirational pull, which is generated by the evaporation of water from the leaves.

**Final Answer**: Water is mainly transported to shoot tips by the help of **transpirational pull**.
