Which of the following is considered as neither prokaryotes nor eukaryotes?
(a) Bacteria
(b) Monera
(c) Fungi
(d) Bacteriophages

Options

A. Bacteria
B. Monera
C. Fungi
D. Bacteriophages.

Answer

To solve the question "Which of the following is considered as neither prokaryotes nor eukaryotes?", we will analyze each option provided:

1. **Understanding Prokaryotes and Eukaryotes**:
- Prokaryotes are organisms that do not have a defined nucleus or membrane-bound organelles. Examples include bacteria.
- Eukaryotes are organisms that have a defined nucleus and membrane-bound organelles. Examples include fungi, plants, and animals.

2. **Analyzing the Options**:
- **(a) Bacteria**: Bacteria are classified as prokaryotes because they lack a nucleus and membrane-bound organelles. Therefore, this option is not correct.
- **(b) Monera**: Monera is a kingdom that includes prokaryotic organisms, such as bacteria. Since Monera consists of prokaryotes, this option is also not correct.
- **(c) Fungi**: Fungi are eukaryotic organisms. They have a defined nucleus and membrane-bound organelles. Thus, this option is not correct.
- **(d) Bacteriophages**: Bacteriophages are viruses that infect bacteria. They are not classified as prokaryotes or eukaryotes because they do not have cellular structures and are not considered living organisms in the traditional sense.

3. **Conclusion**:
- The only option that is neither a prokaryote nor a eukaryote is **(d) Bacteriophages**.

Thus, the correct answer is **(d) Bacteriophages**.
