Mesophyll is differentiated in to palisade and spongy tissues in

Options

A. Extermely xerophytic leaves
B. Hydrophytic leaves
C. Moncot leaves
D. Dicot leaves

Answer

### Step-by-Step Solution:

1. **Understanding Mesophyll**: Mesophyll is the tissue found between the upper and lower epidermis of leaves. It is primarily responsible for photosynthesis and gas exchange.

2. **Differentiation of Mesophyll**: Mesophyll is differentiated into two types of tissues:
- **Palisade Tissue**: This tissue is located just beneath the upper epidermis. It consists of elongated cells that are closely packed together, which maximizes light absorption for photosynthesis.
- **Spongy Tissue**: This tissue is located beneath the palisade tissue. It consists of loosely arranged cells with large air spaces between them, facilitating gas exchange (like oxygen and carbon dioxide) and allowing for the movement of water vapor.

3. **Types of Leaves**: The question asks which type of leaves exhibit this differentiation of mesophyll into palisade and spongy tissues.
- **Xerophytic Leaves**: Adapted to dry environments, may have different adaptations.
- **Hydrophytic Leaves**: Adapted to aquatic environments, typically do not have this differentiation.
- **Monocot Leaves**: Generally have a different structure and do not typically show this differentiation.
- **Dicot Leaves**: Characteristically have both palisade and spongy mesophyll tissues.

4. **Conclusion**: Based on the differentiation of mesophyll into palisade and spongy tissues, the correct answer is **dicot leaves**.

### Final Answer:
Mesophyll is differentiated into palisade and spongy tissues in **dicot leaves**.
