Pollination occuring in closed flowers is

Options

A. Bud pollination
B. Cleistogamy
C. Chasmogamy
D. Allogamy

Answer

To answer the question regarding pollination occurring in closed flowers, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Pollination**: Pollination is the process by which pollen is transferred from the male anther to the female stigma of a flower, leading to fertilization.

2. **Identifying Types of Pollination**: There are different types of pollination, including:
- **Chasmogamy**: Pollination occurs in open flowers.
- **Clistogamy**: Pollination occurs in closed flowers.
- **Allogamy**: Cross-pollination occurs between different plants.
- **Bud Pollination**: Pollination that occurs while the flower is still in bud form.

3. **Focusing on Closed Flowers**: Since the question specifically asks about pollination in closed flowers, we need to focus on the type of pollination that occurs when the flowers do not open.

4. **Defining Clistogamy**: Clistogamy refers to the phenomenon where flowers remain closed and self-pollination occurs. This means that the pollen from the anthers fertilizes the ovules within the same flower without the need for the flower to open.

5. **Conclusion**: Based on the definitions and characteristics, the type of pollination that occurs in closed flowers is **Clistogamy**.

### Final Answer:
Pollination occurring in closed flowers is called **Clistogamy**.
