(a) Monocotyledonous roots have fewer xylem bundles (b) Monocotyledonous roots do not show secondary growth (c) Dicot root has small pith.
Select correct statement.

Options

A. (a) & (c)
B. (b) & (d)
C. (b) & (c)
D. (C) & (d)

Answer

To solve the question, we need to analyze each of the given statements regarding monocotyledonous and dicotyledonous roots:

1. **Statement A**: "Monocotyledonous roots have fewer xylem bundles."
- **Analysis**: Monocotyledonous roots typically have numerous xylem and phloem bundles arranged in a ring. Therefore, this statement is incorrect because it suggests that monocots have fewer xylem bundles when, in fact, they have many.

2. **Statement B**: "Monocotyledonous roots do not show secondary growth."
- **Analysis**: This statement is correct. Monocot roots lack vascular cambium, which is responsible for secondary growth (the formation of secondary xylem and phloem). As a result, monocots do not exhibit secondary growth.

3. **Statement C**: "Dicot root has small pith."
- **Analysis**: This statement is also correct. In dicot roots, the pith is generally not well developed and is smaller compared to that in monocot roots. The pith in dicot roots is mainly composed of polygonal parenchymatous tissue, which serves as a storage unit for food.

**Conclusion**:
- Statement A is incorrect.
- Statement B is correct.
- Statement C is correct.

Thus, the correct statements are B and C.

### Final Answer:
The correct statements are B and C.
