The modified adventitious roots, which originate from the lower nodes of the stem of maize & sugarcane are

Options

A. Stilt root
B. Beaded root
C. Fasciculated root
D. Prop root

Answer

To answer the question about the modified adventitious roots that originate from the lower nodes of the stem of maize and sugarcane, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Type of Roots**:
- The question asks for modified adventitious roots. Adventitious roots are roots that grow from unusual places, such as stems or leaves, rather than from the primary root.

2. **Consider the Plants Mentioned**:
- The plants in question are maize (Zea mays) and sugarcane (Saccharum officinarum). Both of these plants are known for their specific adaptations to their environments.

3. **Examine the Options**:
- The options given are:
- A) Stilt root
- B) Beaded roots
- C) Fasciculated roots
- D) Prop root

4. **Analyze Each Option**:
- **Stilt Roots**: These are roots that grow from the lower nodes of the stem to provide additional support to the plant, especially in weak-stemmed plants like maize and sugarcane.
- **Beaded Roots**: These are not commonly associated with maize or sugarcane.
- **Fasciculated Roots**: These roots are typically found in plants like carrots and are not the type we are looking for.
- **Prop Roots**: While prop roots provide support, they are more commonly associated with plants like banyan trees.

5. **Select the Correct Answer**:
- Based on the analysis, the correct answer is **A) Stilt roots**. These roots help support the plant by anchoring it more firmly into the ground.

### Final Answer:
The modified adventitious roots, which originate from the lower nodes of the stem of maize and sugarcane, are **stilt roots**.
