Which of the following have sunken stomata

Options

A. Nerium
B. Mangifera
C. Hydrilla
D. Zea mays

Answer

**Step-by-Step Solution:**

1. **Understand the Function of Stomata:**
- Stomata are small openings on the surface of leaves that allow for gas exchange, primarily the intake of carbon dioxide (CO2) for photosynthesis and the release of oxygen (O2).

2. **Identify the Types of Plants:**
- The question presents four options: Nerium, Magnifera, Hydrilla, and Zeemage. We need to determine which of these plants have sunken stomata.

3. **Define Sunken Stomata:**
- Sunken stomata are stomata that are located below the surface of the leaf. This adaptation is commonly found in xerophytes (desert plants) to reduce water loss in arid environments.

4. **Analyze Each Option:**
- **Option A: Nerium** - This plant is a xerophyte and is known to have sunken stomata to minimize water loss.
- **Option B: Magnifera** - This plant does not belong to the xerophyte category and has normal stomata.
- **Option C: Hydrilla** - This is an aquatic plant (hydrophyte) and also has normal stomata.
- **Option D: Zeemage** - The characteristics of this plant are not widely recognized, but it is likely not a xerophyte.

5. **Conclusion:**
- Based on the analysis, the only plant with sunken stomata is **Nerium** (Option A).

**Final Answer:**
- The correct answer is **Nerium (Option A)**.
