Supporting roots coming out of the tower nodes of the sugarcane stem are called

Options

A. Prop roots
B. Stilt roots
C. Pneumatophores
D. Fusiform roots

Answer

To answer the question "Supporting roots coming out of the lower nodes of the sugarcane stem are called," we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Type of Plant**: The question refers to sugarcane, which is a type of grass known for its tall, jointed stems.

2. **Understand the Structure of Sugarcane**: Sugarcane stems are characterized by their nodes and internodes. The nodes are the points on the stem where leaves and branches arise.

3. **Recognize the Function of Roots**: The roots that emerge from the lower nodes of the sugarcane stem serve a specific purpose. They provide additional support to the plant, which is important because the stem can be weak and tall.

4. **Identify the Correct Type of Roots**: The roots that emerge from the lower nodes of the sugarcane stem are known as **stilt roots**. These roots help to stabilize the plant and prevent it from falling over.

5. **Eliminate Incorrect Options**:
- **Prop roots**: These arise from branches and provide support but are not the correct answer for sugarcane.
- **Pneumatophores**: These are specialized roots for respiration and are not related to sugarcane.
- **Fusiform roots**: These are storage roots found in plants like radish and are not applicable here.

6. **Conclude the Answer**: Based on the above analysis, the correct answer to the question is **stilt roots**.

### Final Answer:
The supporting roots coming out of the lower nodes of the sugarcane stem are called **stilt roots**.
