Which type of microbes can be grown on nutrient medium to form colonies

Options

A. Bacteria
B. Fungi
C. Viruses
D. 1 & 2

Answer

To answer the question "Which type of microbes can be grown on nutrient medium to form colonies?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Microbes**: Microbes include various types of organisms such as bacteria, fungi, and viruses. Each of these has different growth requirements.

2. **Nutrient Medium**: A nutrient medium is a substance that provides the necessary nutrients for the growth of microorganisms. Common examples include agar plates, which are used to culture bacteria and fungi.

3. **Bacteria Growth**: Bacteria can be cultured on nutrient media. They thrive in environments that provide the right temperature, pH, and nutrients. When grown on agar plates, they form visible colonies.

4. **Fungi Growth**: Similar to bacteria, fungi can also be grown on nutrient media. They require specific nutrients and conditions to grow and can also form colonies on agar.

5. **Viruses Growth**: Unlike bacteria and fungi, viruses cannot be grown on nutrient media. They require a host cell to replicate and cannot survive or multiply outside of a living organism. Therefore, they cannot form colonies on nutrient media.

6. **Conclusion**: Based on the information, the types of microbes that can be grown on nutrient media to form colonies are bacteria and fungi.

### Final Answer:
The correct answer is: **Bacteria and Fungi**.
