Which option provide correct information with respect to prokaryotic cell ?

Options

A. Bacteria, Blue green Algae, Mycolplasma, PPLO are not members of prokaryotes
B. They are generally smaller and multiply more rapidly than the eukaryotic cells
C. All prokaryotes are similar in shape and size
D. All bacterial cells are similar in their shape

Answer

To answer the question regarding which option provides correct information about prokaryotic cells, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Prokaryotic Cells**:
- Prokaryotic cells are characterized by their lack of a true nucleus and membrane-bound organelles. The term "prokaryote" comes from Greek roots: "pro" meaning primitive and "karyon" meaning nucleus.

2. **Analyze the Options**:
- **Option A**: States that bacteria, blue-green algae, mycoplasma, and PPLO are not members of prokaryotes.
- **Evaluation**: This statement is incorrect because all these organisms are indeed prokaryotes.

- **Option B**: States that prokaryotic cells are generally smaller and multiply more rapidly than eukaryotic cells.
- **Evaluation**: This statement is correct. Prokaryotic cells are typically smaller and can reproduce more quickly due to their simpler structure.

- **Option C**: Claims that all prokaryotes are similar in shape and size.
- **Evaluation**: This statement is incorrect. Prokaryotes can vary significantly in shape and size.

- **Option D**: States that all bacterial cells are similar in their shape.
- **Evaluation**: This statement is also incorrect. Bacteria come in various shapes, such as cocci (spherical), bacilli (rod-shaped), and spirilla (spiral).

3. **Conclusion**:
- After evaluating all the options, we find that **Option B** is the only correct statement regarding prokaryotic cells.

### Final Answer:
**Option B**: They are generally smaller and multiply more rapidly than the eukaryotic cells.
