During favourable condition the encysted amoeba divides by multiple fission and produces pseudopodiospores. This phenomenon is known as

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding the Context**: The question is about the reproductive process of encysted amoeba during favorable conditions. It specifically mentions that the amoeba divides by multiple fission and produces pseudopodiospores.

2. **Identifying the Reproductive Process**: The key terms in the question are "multiple fission" and "pseudopodiospores." Multiple fission is a type of asexual reproduction where an organism divides into several parts, each of which can develop into a new individual.

3. **Exploring the Options**: The options provided in the question are budding, sporulation, fragmentation, and regeneration. We need to evaluate each option to find the correct one.

- **Budding**: This is a form of asexual reproduction where a new organism develops from an outgrowth of the parent. It does not involve multiple fission.

- **Fragmentation**: This process involves the breaking of the parent organism into fragments, each of which can grow into a new individual. This is not the same as multiple fission.

- **Regeneration**: This refers to the ability of an organism to regrow lost or damaged parts. It is not a reproductive process.

- **Sporulation**: This is a process where an organism produces spores that can develop into new individuals under favorable conditions. In the case of amoeba, during favorable conditions, it can undergo multiple fission to produce spores.

4. **Conclusion**: Based on the definitions and processes discussed, the correct answer to the question is **sporulation**. This is the phenomenon where the encysted amoeba divides by multiple fission and produces pseudopodiospores.

**Final Answer**: The phenomenon is known as **sporulation**.
