Assured seed set is possible even in absence of pollinators when flower is

Options

A. Amorphophallus
B. Commelina
C. Ficus
D. Vallisneria

Answer

To solve the question regarding assured seed set in the absence of pollinators, we will follow these steps:

### Step-by-Step Solution:

1. **Understanding the Concept of Assured Seed Set**:
- Assured seed set refers to the ability of a plant to produce seeds without the need for pollinators. This can occur through self-pollination.

2. **Identifying Flower Types**:
- There are different types of flowers based on their reproductive strategies. Key types include:
- **Chasmogamous flowers**: These flowers open and allow for cross-pollination.
- **Clistogamous flowers**: These flowers remain closed and typically self-pollinate.

3. **Focusing on Clistogamous Flowers**:
- Clistogamous flowers are crucial for assured seed set in the absence of pollinators. Since these flowers do not open, they rely on self-pollination, ensuring that seeds can be produced without external pollinators.

4. **Analyzing the Given Options**:
- The options provided are:
- Amorphophallus
- Comelina
- Ficus
- Valisenaria
- Among these, we need to identify which flower is clistogamous.

5. **Identifying the Correct Answer**:
- Comelina is known to have clistogamous flowers. Therefore, it is the correct answer as it allows for assured seed set even in the absence of pollinators.

### Final Answer:
The flower that allows for assured seed set even in the absence of pollinators is **Comelina**.
