Paramecium reproduces by

Options

A. asexual reproduction
B. sexual reproduction
C. both (1) and (2)
D. none of the above

Answer

**Step-by-Step Solution:**

1. **Understanding Paramecium**: Paramecium is a single-celled organism that belongs to the group of ciliates. It is commonly found in freshwater environments.

2. **Types of Reproduction**: Paramecium can reproduce in two main ways: asexual reproduction and sexual reproduction.

3. **Asexual Reproduction**: The primary method of asexual reproduction in Paramecium is through binary fission. In this process:
- A fully grown Paramecium divides into two identical daughter cells.
- This division occurs when the organism has reached a certain size and is capable of splitting its cellular contents evenly.

4. **Sexual Reproduction**: Paramecium also has a method of sexual reproduction known as conjugation. In this process:
- Two Paramecium organisms come together and form a temporary union.
- They exchange genetic material, specifically micronuclear elements, which contributes to genetic diversity.

5. **Conclusion**: Since Paramecium can reproduce both asexually (through binary fission) and sexually (through conjugation), the correct answer to the question is that Paramecium reproduces by both methods.

6. **Final Answer**: The correct option is C: both A (asexual reproduction) and B (sexual reproduction).
