Bacteria & yeast are similar to each other in all of the following characteristic except that

Options

A. Both are capable of causing fermentation
B. Both have cell wall
C. Both are prokaryotes
D. Both are unicellular

Answer

To solve the question regarding the similarities and differences between bacteria and yeast, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Organisms**:
- Bacteria belong to the kingdom Monera and are classified as prokaryotes.
- Yeast belongs to the kingdom Fungi and is classified as eukaryotes.

2. **Analyze the Characteristics**:
- Both bacteria and yeast are capable of fermentation. This is a common characteristic.
- Both have a cell wall. However, the composition of the cell wall differs; bacteria have peptidoglycan, while yeast has chitin.
- Both are unicellular organisms. This characteristic is true for both.
- Bacteria are prokaryotes, while yeast are eukaryotes. This is a key difference.

3. **Determine the Odd One Out**:
- The question asks for the characteristic that does not apply to both.
- Since bacteria are prokaryotic and yeast are eukaryotic, the statement "both are prokaryotes" is incorrect.

4. **Conclusion**:
- Therefore, the correct answer to the question is that bacteria and yeast are similar in all characteristics except that both are prokaryotes.

### Final Answer:
The characteristic that does not apply to both bacteria and yeast is that "both are prokaryotes."
