Asexual reproduction mainly takes place in

Options

A. Higher animals
B. lower animals
C. Plants
D. all the above

Answer

To determine where asexual reproduction mainly takes place, we can analyze the options provided: higher animals, lower animals, plants, and all of the above.

### Step-by-Step Solution:

1. **Understanding Asexual Reproduction**:
- Asexual reproduction is a mode of reproduction that involves only one parent. This process allows for the production of offspring without the need for gametes (sperm and egg).
- It is characterized by the use of minimal cellular machinery and energy, making it a simpler and faster method of reproduction.

2. **Identifying Organisms**:
- **Higher Animals**: These are typically more complex organisms that often reproduce sexually. While some higher animals can reproduce asexually (e.g., certain species of lizards), it is not the primary mode of reproduction.
- **Lower Animals**: These organisms, which include many unicellular and simple multicellular organisms, often reproduce asexually. Examples include bacteria (prokaryotes) and many protozoans (eukaryotes).
- **Plants**: Many lower plants (like mosses and ferns) can also reproduce asexually through methods like vegetative propagation. However, higher plants (like angiosperms and gymnosperms) predominantly reproduce sexually.

3. **Conclusion**:
- Given the characteristics of asexual reproduction and the types of organisms, it is evident that asexual reproduction mainly takes place in **lower animals**. They rely on this method to quickly increase their population and enhance their chances of survival.

4. **Final Answer**:
- The correct answer is **lower animals**.
