Bacterial size is

Options

A. `2-10mum`
B. `10-15mum`
C. `100-200mum`
D. `15-50mum`

Answer

**Step-by-Step Solution:**

1. **Understanding Bacteria**: Bacteria are classified as prokaryotes, which means they lack a distinct nucleus and other membrane-bound organelles. They belong to the kingdom Monera.

2. **Size Range of Bacteria**: The size of bacteria can vary significantly depending on the species. However, in general, bacteria are known to be very small organisms.

3. **Specific Size Measurements**: The typical size range for bacteria is approximately 2 to 10 micrometers in length. Additionally, their diameter usually ranges from about 0.2 to 1.5 micrometers.

4. **Evaluating the Options**: Given the options provided:
- Option 1: 2 to 10 micrometers (This matches the typical size range for bacteria.)
- Option 2: 10 to 15 micrometers (This is larger than the typical size range.)
- Option 3: 100 to 200 micrometers (This is significantly larger than the typical size range.)
- Option 4: 15 to 50 micrometers (This is also larger than the typical size range.)

5. **Conclusion**: Based on the information, the correct answer is the first option, which states that the bacterial size is 2 to 10 micrometers.

**Final Answer**: Bacterial size is 2 to 10 micrometers.
