Select the odd one out w.r.t. sub-aerial weak stem.

Options

A. Offsets
B. Stolons
C. Suckers
D. Tendrils

Answer

To solve the question of selecting the odd one out with respect to sub-aerial weak stems, we will analyze each option provided.

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Sub-aerial weak stems** are stems that grow just above the ground and can be easily bent or broken. They typically include structures that help in vegetative reproduction.

2. **Analyze Each Option**:
- **Offset**:
- Definition: A lateral branch of a stem with short internodes, typically found in hydrophytes (plants that grow in water).
- Example: Pistia (water lettuce).
- Conclusion: Offset is a sub-aerial weak stem.

- **Stolen**:
- Definition: A type of sub-aerial stem where lateral branches are arched with elongated internodes.
- Conclusion: Stolen is also a sub-aerial weak stem.

- **Suckers**:
- Definition: Branches that arise from the basal and underground part of the main stem.
- Example: Banana.
- Conclusion: Suckers are sub-aerial weak stems as well.

- **Tendrils**:
- Definition: Aerial structures that are spring-like and help in supporting the plant.
- Conclusion: Tendrils are not sub-aerial weak stems; they are aerial structures.

3. **Identify the Odd One Out**:
- From the analysis, we see that offsets, stolons, and suckers are all sub-aerial weak stems. However, tendrils are not classified as sub-aerial weak stems but rather as aerial structures.

4. **Final Answer**:
- The odd one out is **Tendrils**.
