Coconut , Vallisneria , Ophrys, Amorphophallus, Commelina, bamboo, wheat , rice , Yucca.

Options

A. Seven
B. Ten
C. Four
D. Five

Answer

To determine how many plants from the given list are wind-pollinated, we will analyze each plant one by one.

1. **Coconut**: This plant is primarily insect-pollinated, not wind-pollinated.

2. **Vallisneria**: This aquatic plant is pollinated by water (hydrophilia), not by wind.

3. **Ophrys (Orchids)**: These are primarily insect-pollinated. They have specialized mechanisms to attract pollinators, so they are not wind-pollinated.

4. **Amorphophallus**: This plant is also primarily insect-pollinated, particularly by flies, and is not wind-pollinated.

5. **Commelina**: This plant can undergo self-pollination (autogamy) and has some forms that are wind-pollinated. However, it is not primarily known for wind pollination.

6. **Bamboo**: Bamboo is known to be wind-pollinated (anemophilous).

7. **Wheat**: Wheat is also a well-known wind-pollinated plant.

8. **Rice**: Rice is another plant that is wind-pollinated.

9. **Yucca**: This plant is primarily pollinated by the yucca moth, making it insect-pollinated.

Now, let's summarize the findings:

- **Wind-pollinated plants**: Bamboo, Wheat, Rice
- **Total wind-pollinated plants**: 3

Thus, the answer to the question is that there are **3 wind-pollinated plants** in the list.
