Which type of asexual reproduction is found in Opalina?

Options

A. Regeneration
B. Plasmotomy
C. Budding
D. Fragmentation

Answer

To determine the type of asexual reproduction found in Opalina, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Opalina**: Opalina is a genus of ciliated protozoa that are often studied in biological research. They are known for their unique reproductive methods.

2. **Identify Asexual Reproduction**: Asexual reproduction is a process by which an organism can reproduce without the involvement of gametes (sperm and egg). This can occur through various methods such as binary fission, budding, fragmentation, or other forms.

3. **Explore Multi-nucleated Cells**: In Opalina, the cells are multi-nucleated, meaning that each cell contains multiple nuclei. This characteristic is important for understanding how reproduction occurs in these organisms.

4. **Determine the Reproductive Method**: The reproduction in Opalina occurs through a process where the multi-nucleated cell divides to form daughter cells. This process does not involve meiosis, which is typically associated with sexual reproduction.

5. **Identify the Correct Term**: The specific type of asexual reproduction that occurs in Opalina is known as **plasmotomy**. In plasmotomy, the multi-nucleated cell divides, and each nucleus can give rise to a new organism, leading to the formation of new offspring.

6. **Conclusion**: Therefore, the type of asexual reproduction found in Opalina is **plasmotomy**.

### Final Answer:
The type of asexual reproduction found in Opalina is **plasmotomy**.
