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 regarding the statements about living plant tissue with irregular thickenings, we will analyze each statement one by one to identify the false ones.

### Step-by-Step Solution:

1. **Statement I: The cell wall is rigid without any intercellular spaces.**
- **Analysis:** Collenchyma tissue has thickened cell walls and is known for providing support. It typically does not have intercellular spaces, especially in its mature form. Thus, this statement is **true**.

2. **Statement II: It is found in the form of a single-layered hypodermis of the herbaceous dicotyledonous stem.**
- **Analysis:** Collenchyma is usually found in patches beneath the epidermis, not as a single-layered hypodermis. Therefore, this statement is **false**.

3. **Statement III: It is mostly found in monocots and roots.**
- **Analysis:** Collenchyma is primarily found in dicots, particularly in stems and petioles, rather than being predominantly found in monocots and roots. Hence, this statement is also **false**.

4. **Statement IV: The main function is to provide flexible mechanical support and tensile strength.**
- **Analysis:** The primary role of collenchyma is to provide flexible support and tensile strength to growing parts of the plant. Thus, this statement is **true**.

### Conclusion:
The false statements are:
- **Statement II**: It is found in the form of a single-layered hypodermis of the herbaceous dicotyledonous stem.
- **Statement III**: It is mostly found in monocots and roots.

### Final Answer:
The false statements are **II and III**.
