paramecium reproduces by

Options

A. Multiple fission
B. Conjugation
C. Schizogony
D. Transformation

Answer

**Step-by-Step Solution:**

1. **Understanding Paramecium:** Paramecium is a single-celled organism that belongs to the group of protozoans. It is known for its slipper-like shape and cilia that help in movement and feeding.

2. **Modes of Reproduction:** Paramecium can reproduce through various methods. The main methods include:
- Asexual reproduction (e.g., binary fission)
- Sexual reproduction (e.g., conjugation)

3. **Identifying Asexual Reproduction:** In asexual reproduction, Paramecium typically reproduces by binary fission. This process involves the organism splitting into two identical daughter cells. It is a form of mitotic division where one parent cell divides into two.

4. **Identifying Sexual Reproduction:** Paramecium also reproduces sexually through a process called conjugation. In this process, two Paramecium organisms come together and exchange genetic material. This exchange of genetic material increases genetic diversity.

5. **Conclusion:** The primary method of reproduction in Paramecium is conjugation, which is a form of sexual reproduction. However, it can also reproduce asexually through binary fission.

**Final Answer:** Paramecium reproduces by conjugation (sexual reproduction) and binary fission (asexual reproduction).
