Read the following statements about the living plant tissue which has irregular thickenings and identify the false statement .
I. The cell wall is rigid without any intercellular spaces.
II.It is found in the form of a single - layered hypodermis of the herbaceous dicotyledonous stem.
III. It is mostly found in monocots and roots .
IV The main function in provide flexible mechanical support and tensile strength .

Options

A. I and II
B. II and III
C. III and IV
D. I , II and III

Answer

To solve the question, we need to analyze each statement about the living plant tissue with irregular thickenings, which is collenchyma. We will determine which statement is false.

### Step-by-Step Solution:

1. **Understanding Collenchyma**:
- Collenchyma is a type of living plant tissue that provides support, particularly in young and growing parts of the plant. It is characterized by irregular thickenings in the cell walls.

2. **Analyzing Statement I**:
- **Statement I**: "The cell wall is rigid without any intercellular spaces."
- **Evaluation**: This statement is **true**. Collenchyma has thickened cell walls that provide rigidity, and it typically lacks intercellular spaces.

3. **Analyzing Statement II**:
- **Statement II**: "It is found in the form of a single-layered hypodermis of the herbaceous dicotyledonous stem."
- **Evaluation**: This statement is **false**. While collenchyma can be found in the hypodermis of some dicot stems, it is not strictly a single layer; it can occur in patches or continuous layers.

4. **Analyzing Statement III**:
- **Statement III**: "It is mostly found in monocots and roots."
- **Evaluation**: This statement is **false**. Collenchyma is primarily found in the stems and petioles of dicots, not predominantly in monocots and roots.

5. **Analyzing Statement IV**:
- **Statement IV**: "The main function is to provide flexible mechanical support and tensile strength."
- **Evaluation**: This statement is **true**. Collenchyma does provide flexible support and tensile strength to growing plant parts.

### Conclusion:
The false statements are **II** and **III**. However, since the question asks for a single false statement, we can choose **Statement II** as the primary false statement regarding collenchyma.

### Final Answer:
**The false statement is Statement II: "It is found in the form of a single-layered hypodermis of the herbaceous dicotyledonous stem."**
