Options

A. Chasmogamous flowers
B. Cleistogamous flowers
C. Bisexual flowers
D. Unisexual flowers

Answer

To answer the question regarding the types of flowers that always produce seeds even in the absence of pollinators, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Flower Types**:
- Flowers can be classified into two main types based on their pollination methods: Chasmogamous and Cleistogamous flowers.

2. **Chasmogamous Flowers**:
- These flowers are open and have their anthers and stigmas exposed.
- They typically require cross-pollination, which means they depend on external pollinators (like insects, wind, or water) to transfer pollen from the male part (anther) to the female part (stigma) for fertilization.

3. **Cleistogamous Flowers**:
- In contrast, cleistogamous flowers are closed flowers where the anthers and stigmas are not exposed.
- They primarily undergo self-pollination, meaning that the pollen from the anther fertilizes the ovule of the same flower without the need for external pollinators.

4. **Conclusion**:
- Since cleistogamous flowers do not require pollinators for seed production, they are the correct answer to the question. They can produce seeds even in the absence of pollinators.

### Final Answer:
- The types of flowers which always produce seeds even in the absence of pollinators are **Cleistogamous flowers**.
