Cell walls show unevenly thickened hypodermis in

Options

A. Maize
B. Sunflower
C. Jowar
D. Bajra

Answer

To answer the question "Cell walls show unevenly thickened hypodermis in," we need to analyze the options provided: maize, sunflower, zover, and bajra.

### Step-by-Step Solution:

1. **Understanding Hypodermis**: The hypodermis is a layer of cells located beneath the epidermis in plant stems. It can be composed of different types of tissues, including collenchyma and sclerenchyma.

2. **Identifying Tissue Types**:
- **Collenchyma**: This tissue is characterized by unevenly thickened cell walls and provides support to the plant while allowing for flexibility.
- **Sclerenchyma**: This tissue has uniformly thickened cell walls and provides rigidity and strength.

3. **Analyzing Each Option**:
- **Maize**: In maize, the hypodermis is primarily composed of sclerenchyma, which does not have unevenly thickened walls. Therefore, maize is not the correct answer.
- **Sunflower**: Sunflower stems typically contain collenchyma in the hypodermis, which is known for its unevenly thickened cell walls. This makes sunflower a potential correct answer.
- **Zover**: There is limited information available about the specific histological characteristics of "zover," but it is not commonly known for having collenchyma.
- **Bajra**: Similar to maize, bajra (pearl millet) also has a hypodermis composed of sclerenchyma, which does not exhibit uneven thickening.

4. **Conclusion**: Based on the analysis, the only plant from the options that shows unevenly thickened hypodermis due to the presence of collenchyma is the sunflower.

### Final Answer:
The correct answer is **sunflower**.
