Which of the following is pollinated by water?

Options

A. Zostera
B. Yucca
C. Oxalis
D. Commelina

Answer

To determine which of the following plants is pollinated by water, we need to understand the concept of hydrophily, which is the process of water pollination. Let's analyze the options provided:

1. **Identify the type of pollination**:
- Hydrophily refers to pollination that occurs through water. This is a less common form of pollination compared to others like wind or insect pollination.

2. **Examine the options**:
- **Option A: Zostera** - Zostera is a genus of seagrass that is known to be pollinated by water. It reproduces in aquatic environments and relies on water currents for the transfer of pollen.
- **Option B: Yucca** - Yucca plants are primarily pollinated by specific insects, particularly moths. This is an example of entomophily (insect pollination).
- **Option C: Oxalis** - Oxalis plants also rely on insects, such as bees, for pollination, which is another form of entomophily.
- **Option D: Common Lena** - Common Lena exhibits two types of flowers: clastogamous (self-pollinating) and chasmogamous (pollinated by insects). Therefore, it does not rely on water for pollination.

3. **Conclusion**:
- After analyzing all the options, it is clear that **Zostera** is the only plant listed that is pollinated by water. Therefore, the correct answer is **Option A: Zostera**.
