Choose correct option w.r.t. spongy mesophyll in dicot leaf.

Options

A. Numerous large spaces and air cavities between its cells.
B. A large number of chloroplasts
C. Present on the adaxial surface
D. Vertical and parallel arrangemetn of cells

Answer

To solve the question regarding the spongy mesophyll in a dicot leaf, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Mesophyll**:
- The mesophyll is the ground tissue of a leaf and is primarily responsible for photosynthesis. It consists of two types: palisade mesophyll and spongy mesophyll.

2. **Identifying Spongy Mesophyll**:
- Spongy mesophyll is composed of parenchymatous cells. These cells are characterized by their loosely arranged structure, which allows for air spaces between them.

3. **Characteristics of Spongy Mesophyll**:
- The cells in spongy mesophyll are generally oval or round in shape and are not arranged in a vertical or parallel manner. Instead, they are loosely packed, which creates large air cavities.

4. **Location of Mesophyll Types**:
- In a dicot leaf, the palisade mesophyll is typically found on the adaxial (upper) surface of the leaf, while the spongy mesophyll is located beneath it, closer to the abaxial (lower) surface.

5. **Evaluating Options**:
- When presented with options regarding the spongy mesophyll, we need to look for descriptions that highlight its loose arrangement, presence of air spaces, and its position in the leaf structure.

6. **Conclusion**:
- The correct option regarding the spongy mesophyll will emphasize its loosely arranged cells and the presence of air cavities, distinguishing it from the palisade mesophyll.
