Which of the following group of plants shows entomophily?

Options

A. Vallisneria, Grass, Amorphophallus
B. Amorphophallus, Yucca, Zea mays
C. Wheat, Zostera, Rafflesia
D. Yucca, Ficus, Salvia

Answer

To determine which group of plants shows entomophily, we need to understand what entomophily means. Entomophily is a type of pollination where insects are the primary agents of pollination. Let's analyze the given options step by step:

### Step 1: Understand the Options
The options provided are:
1. Valisneria, grass
2. Amorphophilus, Amorphophilus yucca and geomace
3. Wheat, Joystra, and Rafflesiae
4. Yucca, Ficus, and Salvia

### Step 2: Analyze Each Group
- **Option 1: Valisneria, grass**
- Valisneria is a water plant, and its pollination occurs through water (hydrophily). Grass generally relies on wind for pollination (anemophily). Therefore, this option does not show entomophily.

- **Option 2: Amorphophilus, Amorphophilus yucca and geomace**
- The Amorphophilus plant has a unique relationship with moths, particularly the yucca plant, which is pollinated by specific moths. This indicates that there is insect involvement in pollination. Therefore, this option can be considered as showing entomophily.

- **Option 3: Wheat, Joystra, and Rafflesiae**
- Wheat is primarily wind-pollinated (anemophily). Joystra also relies on water for pollination. Rafflesiae, while it has a unique pollination mechanism involving insects, is not primarily known for its insect pollination. Therefore, this option does not show entomophily.

- **Option 4: Yucca, Ficus, and Salvia**
- Yucca is pollinated by moths, as previously mentioned. Ficus (or fig trees) has a mutualistic relationship with fig wasps, which are essential for its pollination. Salvia also attracts various insects for pollination. Hence, this group shows clear examples of entomophily.

### Step 3: Conclusion
After analyzing all the options, the groups that show entomophily are:
- **Option 2: Amorphophilus, Amorphophilus yucca and geomace**
- **Option 4: Yucca, Ficus, and Salvia**

However, since the question asks for a group, the best answer is **Option 4: Yucca, Ficus, and Salvia**, as it includes multiple plants known for insect pollination.

### Final Answer
The correct answer is **Option 4: Yucca, Ficus, and Salvia**.
