In five kingdom classification, bacteria belong to

Options

A. Monera
B. Protist
C. Plantae
D. Archaea

Answer

**Step-by-Step Solution:**

1. **Understanding the Classification System**: The question pertains to the five kingdom classification system, which categorizes living organisms into five distinct kingdoms based on certain characteristics.

2. **Identifying Bacteria**: Bacteria are unicellular organisms that lack a nucleus and other membrane-bound organelles. They are classified as prokaryotic organisms.

3. **Locating Bacteria in the Five Kingdoms**: In the five kingdom classification, organisms are divided into:
- Monera: Includes prokaryotic organisms (like bacteria).
- Protista: Includes simple eukaryotic organisms.
- Fungi: Includes fungi, which are eukaryotic.
- Plantae: Includes all plants, which are also eukaryotic.
- Animalia: Includes all animals, which are eukaryotic.

4. **Determining the Correct Kingdom for Bacteria**: Since bacteria are unicellular prokaryotes, they are classified under the kingdom Monera.

5. **Evaluating Other Options**:
- Protista is incorrect because it includes eukaryotic organisms.
- Plantae is incorrect as it includes multicellular plants.
- Archaea is not a kingdom in the five kingdom classification; it is a category of bacteria.

6. **Conclusion**: Therefore, the correct answer is that bacteria belong to the kingdom Monera.

**Final Answer**: Option A, Monera.
