Hydrophyte which does not show hydrophily is

Options

A. Water Hyacinth
B. Vallisneria, Hydrilla, Amorphophallus
C. Zostera
D. Hydrilla

Answer

To solve the question "Hydrophyte which does not show hydrophily is:", we will follow these steps:

### Step 1: Understand the Terms
- **Hydrophyte**: A plant that grows in water.
- **Hydrophily**: Pollination that occurs through water.

### Step 2: Identify Hydrophytes
List some common hydrophytes:
- Water Hyacinth (Eichhornia crassipes)
- Vallisneria
- Zostera
- Hydrilla

### Step 3: Analyze Pollination Mechanisms
Determine the pollination method for each hydrophyte:
1. **Water Hyacinth**: Pollination is primarily by insects (entomophily).
2. **Vallisneria**: Pollination occurs through water (hydrophily).
3. **Zostera**: Pollination occurs through water (hydrophily).
4. **Hydrilla**: Pollination occurs through water (hydrophily).

### Step 4: Identify the Correct Answer
From the analysis:
- Water Hyacinth is a hydrophyte that does not exhibit hydrophily because it relies on insect pollination.
- Vallisneria, Zostera, and Hydrilla all exhibit hydrophily.

### Conclusion
The hydrophyte that does not show hydrophily is **Water Hyacinth**.
