Can microorganisms be seen with the naked eye? If not, how can they be seen?

Explanation

**Step-by-Step Solution:**

1. **Understanding Microorganisms**: Microorganisms are tiny living organisms that cannot be seen with the naked eye due to their small size. They are referred to as "micro" organisms because they are microscopic in nature.

2. **Naked Eye Limitations**: The human eye has limitations in terms of resolution and can only see objects that are larger than a certain size. Microorganisms, such as bacteria, algae, and protozoa, are much smaller than this size threshold, making them invisible to the naked eye.

3. **Using Instruments**: To observe microorganisms, we need to use special instruments. The most common tools for this purpose are:
- **Microscope**: A microscope is an optical instrument that uses lenses to magnify small objects, allowing us to see microorganisms clearly.
