Answer

To determine how many plants from the given list are insect-pollinated, we will analyze each plant one by one based on their pollination mechanisms.

### Step-by-Step Solution:

1. **List the Plants**:
- Sunflower
- Coconut
- Water lily
- Water hyacinth
- Vallisneria
- Ophrys
- Papaya
- Cotton
- Banana
- Adansonia
- Bombax
- Bamboo
- Wheat
- Hydrilla

2. **Identify Pollination Mechanisms**:
- **Sunflower**: Insect-pollinated (mainly by bees).
- **Coconut**: Insect-pollinated (though it can also be wind-pollinated).
- **Water lily**: Insect-pollinated (but can also be wind-pollinated).
- **Water hyacinth**: Insect and wind-pollinated.
- **Vallisneria**: Water-pollinated (not insect-pollinated).
- **Ophrys (Orchids)**: Insect-pollinated.
- **Papaya**: Insect and wind-pollinated.
- **Cotton**: Self-pollinated (not insect-pollinated).
- **Banana**: Pollinated by bats (not insect-pollinated).
- **Adansonia (Baobab)**: Pollinated by bats (not insect-pollinated).
- **Bombax**: Insect, bat, and bird-pollinated.
- **Bamboo**: Wind-pollinated (not insect-pollinated).
- **Wheat**: Wind-pollinated (not insect-pollinated).
- **Hydrilla**: Water-pollinated (not insect-pollinated).

3. **Count the Insect-Pollinated Plants**:
- From the analysis, the insect-pollinated plants are:
- Sunflower
- Coconut
- Water lily
- Water hyacinth
- Ophrys
- Papaya
- Bombax
- Total: 7 insect-pollinated plants.

4. **Conclusion**:
- The total number of insect-pollinated plants in the list is **7**.

### Final Answer:
**7**
