Kingdom(s) containing microbes are

Options

A. Monera
B. Protista
C. Fungi
D. 1, 2 & 3

Answer

To answer the question regarding the kingdoms containing microbes, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Classification System**: Familiarize yourself with the five-kingdom classification system proposed by Robert Whittaker, which includes Monera, Protista, Fungi, Plantae, and Animalia.

2. **Identify Microbes**: Recognize that microbes are generally defined as microscopic organisms, which include bacteria, archaea, fungi, and some protists.

3. **Examine Each Kingdom**:
- **Kingdom Monera**: This kingdom includes prokaryotic organisms, primarily bacteria and archaea, which are indeed classified as microbes.
- **Kingdom Protista**: This kingdom contains unicellular and simple multicellular organisms, including some protozoans and algae. While some of these can be considered microbes, they are not the primary focus of the term "microbes."
- **Kingdom Fungi**: This kingdom includes both unicellular (like yeasts) and multicellular fungi. Yeasts can be classified as microbes, but the kingdom as a whole is not exclusively microbial.
- **Kingdom Plantae and Animalia**: These kingdoms consist of multicellular organisms and do not contain microbes.

4. **Conclusion**: Based on the classification, the kingdom that exclusively contains microbes is **Monera**. While Protista and Fungi may contain some microbial forms, they are not entirely composed of microbes.

5. **Final Answer**: The correct answer is **Kingdom Monera**.
