Identify the correct pair of statement
(i) pericyle parenchymatous in dicot root but sclerenchymatous in mature monocot root
(ii) pericycle of both dicot and monocot root produces lateral roots during secondary growth
(iii) All cells of dicot root endodermis are passage cells
(iv) Xylem is produced in centripetal manner in roots of fruit bearing plants

Options

A. ii and iii
B. iii and iv
C. I and ii
D. I and iv

Answer

To solve the question regarding the correct pair of statements about plant anatomy, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Analyzing Statement (i)**:
- The statement claims that the pericycle is parenchymatous in dicot roots but sclerenchymatous in mature monocot roots.
- **Evaluation**: This statement is **correct**. In dicot roots, the pericycle is indeed composed of parenchyma cells, while in mature monocot roots, it becomes sclerenchymatous.

2. **Analyzing Statement (ii)**:
- This statement suggests that the pericycle of both dicot and monocot roots produces lateral roots during secondary growth.
- **Evaluation**: This statement is **incorrect**. In dicots, the pericycle does contribute to the formation of lateral roots, but this occurs during primary growth, not secondary growth. In monocots, lateral roots typically arise from the pericycle as well, but the emphasis on secondary growth makes this statement misleading.

3. **Analyzing Statement (iii)**:
- This statement asserts that all cells of the dicot root endodermis are passage cells.
- **Evaluation**: This statement is **incorrect**. In dicot roots, not all endodermal cells are passage cells; only some lack the Casparian strip and are termed passage cells.

4. **Analyzing Statement (iv)**:
- The statement claims that xylem is produced in a centripetal manner in the roots of fruit-bearing plants.
- **Evaluation**: This statement is **correct**. In angiosperms, including fruit-bearing plants, xylem develops from the periphery towards the center, which is indeed a centripetal pattern.

### Conclusion:
Based on the evaluations:
- Statement (i) is correct.
- Statement (ii) is incorrect.
- Statement (iii) is incorrect.
- Statement (iv) is correct.

Thus, the correct pair of statements is **(i) and (iv)**. Therefore, the correct option is **option number 4**.
