Assured seed set even in absence of pollinators occurs in

Options

A. Chasmogamous flowers
B. Cross pollinating flowers
C. Cleistogamous flowers
D. Dichogamous flowers

Answer

To solve the question "Assured seed set even in absence of pollinators occurs in", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of Flowers**:
- There are two main types of flowers based on their pollination mechanisms: chasmogamous and cleistogamous flowers.
- Chasmogamous flowers have exposed anthers and stigma, allowing for both self-pollination and cross-pollination, but they depend on external agents (like pollinators) for pollination.

2. **Identify Cleistogamous Flowers**:
- Cleistogamous flowers are those that do not open and have their reproductive organs enclosed. This means they do not rely on external agents for pollination.
- These flowers can self-pollinate, ensuring that seeds are set even in the absence of pollinators.

3. **Conclusion**:
- Since the question asks for assured seed set without pollinators, the correct answer is cleistogamous flowers. They can produce seeds without the need for pollination from external sources.

### Final Answer:
The assured seed set even in the absence of pollinators occurs in **Cleistogamous flowers**.
