A leaf showing stomata and cuticle on upper epidermis, raphides in the mesophyll and diaphragm cells, belongs to a plant that probably is a

Options

A. Mesophyte
B. Floating hydrophyte
C. Submerged hydrophyte
D. Succulent xerophyte

Answer

To determine the type of plant based on the characteristics of its leaf, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Key Features of the Leaf**: The question states that the leaf has stomata and a cuticle on the upper epidermis, raphides in the mesophyll, and diaphragm cells.

2. **Analyze the Stomata Location**:
- Stomata are small openings that allow for gas exchange. The presence of stomata on the upper epidermis is significant.
- In most mesophytes, stomata are typically found on the lower epidermis to minimize water loss.

3. **Evaluate the Types of Plants**:
- **Mesophytes**: Generally have stomata on the lower epidermis. This option can be eliminated.
- **Floating Hydrophytes**: These plants have stomata on the upper epidermis to facilitate gas exchange while floating on water. This option is plausible.
- **Submerged Hydrophytes**: These plants live entirely underwater and do not have stomata on the upper surface. This option can be eliminated.
- **Succulent Xerophytes**: These plants are adapted to dry conditions and usually have stomata covered by hairs to reduce evaporation. This option can also be eliminated.

4. **Conclusion**: Based on the analysis, the plant that likely has a leaf showing stomata and cuticle on the upper epidermis, raphides in the mesophyll, and diaphragm cells is a **floating hydrophyte**.

### Final Answer:
The plant probably is a **floating hydrophyte**.
