Read the following pairs of examples of organisms. The pair that belongs to group prokaryotes is......

Options

A. moss and sponge
B. yeast and Amoeba
C. bacteria and blue-green alga
D. penicillium and Spirogyra

Answer

To determine which pair of organisms belongs to the group prokaryotes, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Prokaryotes**: Prokaryotes are simple, primitive organisms that lack a well-defined nucleus. Their genetic material (DNA) is not enclosed within a nuclear membrane and is typically found in a region called the nucleoid.

2. **Analyze the Options**: We need to evaluate each pair of organisms provided in the question to see which one consists of prokaryotic organisms.

3. **Option 1: Moss and Sponges**:
- **Moss**: A plant, belongs to the plant kingdom (Eukaryote).
- **Sponges**: An animal, belongs to the animal kingdom (Eukaryote).
- **Conclusion**: This pair is not prokaryotic.

4. **Option 2: Yeast and Amoeba**:
- **Yeast**: A fungus, belongs to the kingdom Fungi (Eukaryote).
- **Amoeba**: A single-celled organism, belongs to the kingdom Protista (Eukaryote).
- **Conclusion**: This pair is not prokaryotic.

5. **Option 3: Bacteria and Blue Green Algae**:
- **Bacteria**: A classic example of prokaryotes.
- **Blue Green Algae (Cyanobacteria)**: Also classified as prokaryotes.
- **Conclusion**: This pair is indeed prokaryotic.

6. **Option 4: Panacea and Spirogyra**:
- **Panacea**: A fungus, belongs to the kingdom Fungi (Eukaryote).
- **Spirogyra**: A green algae, belongs to the plant kingdom (Eukaryote).
- **Conclusion**: This pair is not prokaryotic.

7. **Final Answer**: The pair that belongs to the group prokaryotes is **Bacteria and Blue Green Algae**.
