Pollination occurs by pseudocopulation mechanism in

Options

A. ophrys
B. fig
C. mango
D. Zea mays

Answer

### Step-by-Step Solution:

1. **Understanding Pseudocopulation**:
- Pseudocopulation refers to a mechanism where a male insect is attracted to a flower that mimics the appearance of a female insect. The term "pseudo" means false, and "copulation" refers to sexual intercourse.

2. **Identifying the Options**:
- The question provides four options:
1. Ophrys
2. Pig
3. Mango
4. Zemes

3. **Analyzing Each Option**:
- **Ophrys**: This is a genus of orchids known for their flowers that resemble female insects. The male insects are attracted to these flowers, mistaking them for females, which leads to pollination.
- **Pig**: Not a plant; therefore, it cannot be involved in pollination.
- **Mango**: A flowering plant, but it does not use pseudocopulation for pollination.
- **Zemes**: This does not refer to any known plant associated with pseudocopulation.

4. **Conclusion**:
- Based on the analysis, the only option that involves pseudocopulation is **Ophrys**. The male insects are tricked into attempting to mate with the flower, which results in the transfer of pollen.

5. **Final Answer**:
- Pollination occurs by pseudocopulation mechanism in **Ophrys**.
