monocot root differs from dicot root in having

Options

A. Open vascular bundles
B. Scattered vaascular 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 options provided and identify the correct differences between monocot and dicot roots.

### Step-by-Step Solution:

1. **Understanding Monocot and Dicot Roots**:
- Monocots (monocotyledons) and dicots (dicotyledons) are two major groups of flowering plants that differ in various anatomical features, including their root structures.

2. **Analyzing the Options**:
- **Option 1: Open vascular bundle**:
- Open vascular bundles are characterized by the presence of cambium, which allows for secondary growth. This feature is generally associated with dicots rather than monocots.
- **Option 2: Scattered vascular bundle**:
- Monocots typically have scattered vascular bundles throughout the stem and roots, while dicots have vascular bundles arranged in a ring. However, this feature is not exclusive to monocots, as some dicots can also exhibit scattered vascular bundles.
- **Option 3: Well-developed pith**:
- Monocot roots usually have a well-developed pith, which is a central region of parenchyma cells. In contrast, dicot roots typically do not have a well-developed pith.
- **Option 4: Radially arranged vascular bundle**:
- In dicot roots, the vascular bundles are arranged in a radial pattern, while monocots do not exhibit this arrangement.

3. **Identifying the Correct Answer**:
- After analyzing the options, the correct answer is **Option 3: Well-developed pith**. This is a distinguishing feature of monocot roots compared to dicot roots.

### Final Answer:
Monocot roots differ from dicot roots in having a well-developed pith.
