Hydrophyte with both hydrophytic and xerophytic traits is

Options

A. Agave
B. Nerium
C. Vallisneria
D. None of the above.

Answer

To solve the question "Hydrophyte with both hydrophytic and xerophytic traits is," we need to analyze the options provided and understand the definitions of hydrophytes, xerophytes, and mesophytes.

### Step-by-Step Solution:

1. **Understand the Definitions**:
- **Hydrophytes**: These are plants that thrive in water or very moist conditions. They have adaptations that allow them to live in aquatic environments. Examples include *Hydrilla* and *Typha*.
- **Xerophytes**: These are plants adapted to survive in dry environments. They have features that minimize water loss, such as thick cuticles and reduced leaf surface areas. Examples include *Opuntia* and *Asparagus*.
- **Mesophytes**: These plants are adapted to moderate conditions, neither too wet nor too dry. They can survive in both moist and dry environments. Examples include *corn* and *maize*.

2. **Analyze the Options**:
- **Agave**: This is a succulent plant found in arid regions, thus it is classified as a xerophyte. It does not possess hydrophytic traits.
- **Nerium**: This plant is also found in dry areas and is adapted to desert conditions, making it a xerophyte as well. It lacks hydrophytic traits.
- **Vallisneria**: This plant grows in freshwater environments, making it a hydrophyte. It does not have xerophytic traits.
- **None of the Above**: This option suggests that none of the listed plants exhibit both hydrophytic and xerophytic traits.

3. **Conclusion**:
- After analyzing all the options, we find that none of them possess both hydrophytic and xerophytic traits. Therefore, the correct answer is **None of the Above**.

### Final Answer:
The hydrophyte with both hydrophytic and xerophytic traits is **None of the Above**.
