In submerged hydrophytes the stomata occur

Options

A. On Iower surface
B. On the upper surface
C. No where
D. On both the surface.

Answer

**Step-by-Step Solution:**

1. **Understanding Hydrophytes**: Begin by defining what hydrophytes are. Hydrophytes are plants that are adapted to live in aquatic environments. They can be fully submerged in water or partially submerged.

2. **Identifying Stomata**: Stomata are small openings on the surfaces of leaves that allow for gas exchange (such as oxygen and carbon dioxide) and transpiration (water loss).

3. **Stomata in Submerged Hydrophytes**: In the case of submerged hydrophytes, they are fully underwater and do not have stomata. Instead of relying on stomata for gas exchange, these plants absorb water, nutrients, and dissolved gases directly through their surface cells.

4. **Comparison with Other Plants**: Some hydrophytes, like water lilies, have stomata, but they are located only on the upper surface of the leaves, which are above the water. However, submerged hydrophytes do not have stomata at all.

5. **Conclusion**: Therefore, the correct answer to the question is that in submerged hydrophytes, stomata occur "nowhere."

**Final Answer**: In submerged hydrophytes, stomata occur nowhere.
