Fusion of male and female pronuclei of two conjugate Paramecia is known as

Options

A. plasmogamy
B. Fertilization
C. triple fusion
D. Amphimixis.

Answer

To answer the question about the fusion of male and female pronuclei of two conjugate Paramecia, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Terms**:
- The question refers to the fusion of male and female pronuclei in Paramecia. It is important to understand what pronuclei are. Pronuclei are the nuclei of the male and female gametes before they fuse during fertilization.

2. **Identifying the Processes**:
- The options provided in the question include terms like plasmogamy, fertilization, triple fusion, and amphimixes. We need to analyze each term to find the correct one.

3. **Analyzing Plasmogamy**:
- Plasmogamy refers to the fusion of the cytoplasm of two cells. This is not specific to the fusion of pronuclei and is not the correct answer for this question.

4. **Analyzing Fertilization**:
- Fertilization typically refers to the fusion of male and female gametes, such as sperm and ovum in higher animals. However, in the context of Paramecia, it is more specific to the fusion of pronuclei rather than the gametes themselves.

5. **Analyzing Triple Fusion**:
- Triple fusion occurs in angiosperms and involves the fusion of three nuclei. This is not relevant to Paramecia and does not apply to the question.

6. **Identifying the Correct Term - Amphimixes**:
- The correct term for the fusion of male and female pronuclei in conjugate Paramecia is "amphimixes". The prefix "amphi-" means "two", and "mixes" refers to fusion. Thus, amphimixes specifically describes the process we are looking for.

7. **Conclusion**:
- Therefore, the fusion of male and female pronuclei of two conjugate Paramecia is known as **amphimixes**.

### Final Answer:
The fusion of male and female pronuclei of two conjugate Paramecia is known as **amphimixes**.
