Even in absence of pollinating agents seed-setting is assured in

Options

A. Commelina
B. Zostera
C. Salvia
D. Fig

Answer

To answer the question "Even in absence of pollinating agents seed-setting is assured in?", we need to understand the concept of clistogamous flowers and the different types of pollination.

### Step-by-Step Solution:

1. **Understanding Seed Setting**: Seed setting refers to the process of producing seeds after fertilization. It is crucial for the reproduction of flowering plants.

2. **Identifying Clistogamous Flowers**: Clistogamous flowers are a type of flower that remains closed and does not open. Because they do not open, they do not require external pollinating agents (like insects or wind) for fertilization.

3. **Analyzing the Options**:
- **Camelina**: This is a type of clistogamous flower. Since it remains closed, seed setting occurs without the need for pollinators.
- **Jostera**: This is a marine grass that relies on water for pollination (hydrophily), meaning it requires an external agent for pollination.
- **Salvia**: This plant relies on insects for pollination (entomophily), which means it also requires an external pollinating agent.
- **Fig**: The fig tree relies on wasps for pollination, which again means it requires an external pollinating agent.

4. **Conclusion**: Since only Camelina (the first option) is a clistogamous flower that can set seeds without the involvement of pollinators, the correct answer is **Camelina**.

### Final Answer:
Even in the absence of pollinating agents, seed-setting is assured in **Camelina**.
