Among the following which one is not a method of asexual reproduction ?

Options

A. Budding
B. Layering
C. Sowing
D. Binary fission

Answer

To determine which option is not a method of asexual reproduction, we will analyze each of the provided options: budding, layering, sowing, and binary fission.

### Step-by-Step Solution:

1. **Understanding Asexual Reproduction**:
- Asexual reproduction is a mode of reproduction that does not involve the fusion of gametes. It results in offspring that are genetically identical to the parent organism.

2. **Analyzing the Options**:
- **Budding**: This is a form of asexual reproduction where a new organism develops from an outgrowth or bud on the parent organism. This method is commonly seen in organisms like yeast and hydra.
- **Layering**: This is a method of plant propagation where a part of the stem is induced to root while still attached to the parent plant. This is also a form of asexual reproduction.
- **Sowing**: This refers to the process of planting seeds in the soil. Seeds are produced as a result of sexual reproduction, as they are formed from the fertilization of gametes.
- **Binary Fission**: This is a method of asexual reproduction commonly found in single-celled organisms like bacteria, where the organism divides into two identical daughter cells.

3. **Identifying the Incorrect Option**:
- Among the options, **sowing** is the only method that involves sexual reproduction, as it pertains to the planting of seeds that are produced through the fertilization process.

4. **Conclusion**:
- Therefore, the option that is not a method of asexual reproduction is **sowing**.

### Final Answer:
**Sowing** is not a method of asexual reproduction.
