Binary fission in Amoeba occurs by

Options

A. Mitosis
B. Meiosis
C. Amitosis
D. None of the above.

Answer

**Step-by-Step Solution:**

1. **Understanding Binary Fission:**
- Binary fission is a method of asexual reproduction where a single parent cell divides into two equal daughter cells. This process is commonly observed in unicellular organisms like Amoeba.

2. **Identifying the Process of Cell Division:**
- The question asks how binary fission occurs in Amoeba. We need to evaluate the options provided: mitosis, meiosis, amitosis, or none of the above.

3. **Evaluating Mitosis:**
- Mitosis is a type of cell division that results in two daughter cells that are identical to the parent cell. It involves the formation of spindle fibers and is an equational division, meaning the chromosome number remains the same.

4. **Evaluating Meiosis:**
- Meiosis is a reductional division that results in daughter cells with half the chromosome number of the parent cell. It also involves spindle fiber formation, which is not characteristic of binary fission.

5. **Evaluating Amitosis:**
- Amitosis is a simpler form of cell division where the nucleus divides directly into two without the formation of spindle fibers. This process is more aligned with the nature of binary fission.

6. **Conclusion:**
- Since binary fission in Amoeba occurs without the formation of spindle fibers, the correct answer is **amitosis**. Therefore, the answer to the question is option C: amitosis.
