monocot root differs from dicot root in having

Options

A. open vascular bundles
B. scattered vascular bundles.
C. well developed pith
D. radially arranged vascular bundles.

Answer

To answer the question "Monocot root differs from dicot root in having," we will analyze the characteristics of monocot and dicot roots step by step.

### Step-by-Step Solution:

1. **Understand the Structure of Monocot and Dicot Roots**:
- Monocot roots and dicot roots have different structural features. It is essential to know these differences to answer the question correctly.

2. **Identify Key Features**:
- Monocot roots typically have a pith, which is a soft tissue made up of parenchyma cells. This pith is responsible for the storage and transportation of nutrients.
- In contrast, dicot roots usually do not have a pith.

3. **Examine the Options Provided**:
- The options given are:
a. Open vascular bundle
b. Scattered vascular bundle
c. Well-developed pith
d. Radially arranged vascular bundles

4. **Analyze Each Option**:
- **Option A (Open vascular bundle)**: This is incorrect. Both monocots and dicots can have open vascular bundles, but this is not a distinguishing feature.
- **Option B (Scattered vascular bundle)**: This is characteristic of monocots, but it does not specifically answer the question about what monocots have that dicots do not.
- **Option C (Well-developed pith)**: This is correct. Monocots have a well-developed pith, while dicots do not.
- **Option D (Radially arranged vascular bundles)**: This is characteristic of dicots, not monocots.

5. **Conclusion**:
- The correct answer is **Option C: Well-developed pith**. Monocot roots differ from dicot roots in having a well-developed pith.
