In leaves, the ground tissue comprises of

Options

A. Mesophyll,vascular bundles only
B. Only vascular bundles
C. Only mesophyll
D. Xylem fibres, phloem fibres & Sclereids only

Answer

**Step-by-Step Solution:**

1. **Understanding Ground Tissue**: Ground tissue in plants is the tissue that is neither dermal nor vascular. It primarily functions in photosynthesis, storage, and support.

2. **Identifying Components of Ground Tissue in Leaves**: In leaves, the ground tissue is mainly composed of mesophyll, which is the tissue responsible for photosynthesis.

3. **Types of Mesophyll**: Mesophyll is further divided into two types:
- **Palisade Mesophyll**: This layer is located just beneath the upper epidermis and contains tightly packed chlorenchyma cells that are rich in chlorophyll, facilitating efficient photosynthesis.
- **Spongy Mesophyll**: This layer is located beneath the palisade mesophyll and contains loosely arranged cells with air spaces that allow for gas exchange.

4. **Conclusion**: Therefore, in leaves, the ground tissue primarily comprises mesophyll tissue, which includes both palisade and spongy mesophyll.

5. **Eliminating Other Options**: The other options provided (vascular bundles, xylem fibers, phloem fibers, and sclerids) do not constitute ground tissue. Vascular bundles are part of the vascular tissue system, while fibers and sclerids are types of supportive tissues.

**Final Answer**: In leaves, the ground tissue comprises only mesophyll.
