Transportation pull is well - developed in vessels . This is because water possess

Options

A. High tensile strength and low capillarity
B. High tensile strength and high capillarity
C. Low tensile strength and high capillarity
D. Low tensile strength and low capillarity

Answer

To solve the question regarding why transportation pull is well-developed in vessels due to the properties of water, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Concept of Transportation Pull**:
- Transportation pull refers to the mechanism by which water and nutrients are drawn up from the roots of a plant to its leaves. This process is crucial for plant health and growth.

2. **Identifying Key Properties of Water**:
- The two main properties of water that facilitate this process are **tensile strength** and **capillarity**.
- **Tensile strength** refers to the ability of water molecules to resist being pulled apart. This is due to the cohesive forces between water molecules.
- **Capillarity** is the ability of water to move through narrow spaces against gravity, which is essential for water transport in small vessels.

3. **Analyzing the Options**:
- Option 1: High tensile strength and low capillarity.
- Option 2: High tensile strength and high capillarity.
- Option 3: Low tensile strength and high capillarity.
- Option 4: Low tensile strength and low capillarity.

4. **Evaluating Each Option**:
- **Option 1** is incorrect because while it mentions high tensile strength, low capillarity would hinder water movement.
- **Option 2** is correct because it states that water has both high tensile strength and high capillarity, which are essential for effective transportation.
- **Option 3** is incorrect as low tensile strength would not support the cohesion needed for water transport.
- **Option 4** is also incorrect for the same reason as Option 3.

5. **Conclusion**:
- The correct answer is **Option 2: High tensile strength and high capillarity**. These properties of water enable effective transportation pull in vessels.
