Options

A. Procaryotes only
B. Eucaryotes only
C. Both A and B
D. Mesocaryotes only.

Answer

**Step-by-Step Solution:**

1. **Understanding Kingdom Monera**: Kingdom Monera is one of the five kingdoms proposed by Robert Whittaker in his classification system. It is essential to recognize that this kingdom is distinct from others based on specific characteristics.

2. **Characteristics of Organisms in Kingdom Monera**: Organisms classified under Kingdom Monera are primarily unicellular and prokaryotic. This means they consist of a single cell and lack a true nucleus and membrane-bound organelles.

3. **Defining Prokaryotes**: Prokaryotes are organisms that do not have a membrane-bound nucleus. Instead, their genetic material is located in a region called the nucleoid. They also lack other membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus.

4. **Examples of Kingdom Monera**: The most common examples of organisms in this kingdom include bacteria and blue-green algae (cyanobacteria). These organisms play vital roles in various ecological processes.

5. **Conclusion**: Based on the characteristics and examples discussed, it is clear that Kingdom Monera includes only prokaryotes. Therefore, the correct answer to the question is "prokaryotes only."

**Final Answer**: Kingdom Monera includes prokaryotes only.
