In leaves, the ground tissue constitute of this walled parenchymatous chloroplast containing cells and is called __________

Options

A. Mesophyll
B. Epidermis
C. Stomatal apparatus
D. Bundle sheath extension

Answer

**Step-by-Step Solution:**

1. **Understanding Ground Tissue**: The ground tissue in plants is primarily made up of simple permanent tissues such as parenchyma, collenchyma, and sclerenchyma. In the context of leaves, the ground tissue plays a crucial role in photosynthesis and storage.

2. **Identifying the Cells in Leaves**: In leaves, the ground tissue consists of parenchymatous cells that contain chloroplasts. These cells are essential for photosynthesis as they are responsible for capturing light energy.

3. **Defining Mesophyll**: The internal ground tissue of leaves is known as mesophyll. It is located between the upper and lower epidermal layers of the leaf.

4. **Types of Mesophyll**: Mesophyll is composed of two types of tissues:
- **Palisade Mesophyll**: This is the upper layer of mesophyll, consisting of elongated chlorenchyma cells that contain a high density of chloroplasts, making them the primary site for photosynthesis.
- **Spongy Mesophyll**: This is the lower layer, which has a looser arrangement of cells and air spaces that facilitate gas exchange.

5. **Conclusion**: Given the context of the question, the ground tissue in leaves that consists of parenchymatous chloroplast-containing cells is referred to as **mesophyll**.

**Final Answer**: Mesophyll
