Given below are the pairs of plants with sub-aerial stems. Find the dissimilar pair w.r.t. the modification.

Options

A. Mint, Jasmine
B. Pistia, Eichhornia
C. Banana, Grass
D. Both (1) & (3)

Answer

To solve the problem of identifying the dissimilar pair of plants with sub-aerial stems based on their modifications, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of Sub-aerial Stem Modifications**:
- Sub-aerial stems can be modified into various forms such as stolons, runners, offsets, and suckers. Each type has distinct characteristics and functions.

2. **Analyze the Given Pairs**:
- The pairs of plants provided are:
- Mint and Jasmine
- Pistia and Ignoria
- Banana and Grass

3. **Identify the Modification for Each Pair**:
- **Mint and Jasmine**: Both belong to the modification called **stolons**. Stolons are horizontal stems that grow along the surface of the soil.
- **Pistia and Ignoria**: Both belong to the modification known as **offsets**. Offsets are short lateral branches that grow from the base of the parent plant.
- **Banana and Grass**: Banana belongs to the modification called **suckers**, which are vertical shoots that arise from the base of the plant. Grass, on the other hand, belongs to the modification known as **runners**, which are horizontal stems that grow along the ground.

4. **Determine the Dissimilar Pair**:
- Comparing the modifications:
- Mint and Jasmine (stolons) - Similar
- Pistia and Ignoria (offsets) - Similar
- Banana (suckers) and Grass (runners) - Dissimilar

5. **Conclusion**:
- The dissimilar pair with respect to the modification is **Banana and Grass**.

### Final Answer:
The dissimilar pair with respect to the modification is **Banana and Grass**.
