For selecting the correct answer, use the following code:
- a)Both assertion and reason are correct and the reason is the correct explanation for assertion
- b)Assertion is correct but the reason is incorrect.
- c)Both assertion and reason are correct but the reason is not the correct explanation for the assertion.

Explanation:
• Prokaryotic cells, which are found in bacteria and archaea, lack the membrane-bound organelles that are present in eukaryotic cells. These organelles include the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, and lysosomes.
• The cytoplasm of prokaryotic cells does not show a streaming movement, which is a characteristic of eukaryotic cells. In eukaryotic cells, the cytoplasmic streaming is driven by motor proteins that move along actin filaments and microtubules.
• The absence of membrane-bound organelles in prokaryotic cells is related to their small size and simpler structure. They are able to carry out all their necessary functions within the cytoplasm without the need for specialized compartments.
• The lack of cytoplasmic streaming in prokaryotic cells is also related to their small size, as diffusion is sufficient for most of their metabolic processes.
Assertion (A): Prokaryotic cells have no membrane-bound organelles.
Reason (R): The cytoplasm of prokaryotic cells does not show a streaming movement.
The correct answer is option 'A'. Both the assertion and reason are correct, and the reason is the correct explanation for the assertion.

Prokaryotic cells and membrane-bound organelles
Assertion (A): Prokaryotic cells have no membrane-bound organelles.
Reason (R): The cytoplasm of prokaryotic cells does not show a streaming movement.
The correct answer is option 'A', which means that both the assertion and reason are correct and the reason is the correct explanation for the assertion.
Explanation:
Prokaryotic cells are cells that lack a nucleus and other membrane-bound organelles. They are found in bacteria and archaea. Here are some explanations that support the assertion and reason given in the question:
• Assertion (A): Prokaryotic cells have no membrane-bound organelles.
- Prokaryotic cells have no nucleus, which means that their DNA is not enclosed within a membrane-bound organelle.
- Prokaryotic cells also lack other membrane-bound organelles, such as mitochondria, chloroplasts, endoplasmic reticulum, and Golgi apparatus, which are found in eukaryotic cells.
- Instead, prokaryotic cells have a simpler internal structure, with their genetic material located in a region of the cytoplasm called the nucleoid.
• Reason (R): The cytoplasm of prokaryotic cells does not show a streaming movement.
- Cytoplasmic streaming is the movement of cytoplasm within a cell, which is important for the distribution of nutrients, waste products, and organelles.
- The absence of cytoplasmic streaming in prokaryotic cells is due to their smaller size and simpler internal structure, which do not require the same level of movement as eukaryotic cells.
- Therefore, the lack of membrane-bound organelles in prokaryotic cells is related to the absence of cytoplasmic streaming, as both are adaptations to the simpler structure and smaller size of these cells.
In conclusion, the assertion and reason given in the question are both correct, and the reason provides a correct explanation for the assertion.
Assertion (A): Prokaryotic cells have no membrane-bound organelles.
Reason (R): The cytoplasm of prokaryotic cells does not show a streaming movement.
The correct answer is option 'A', which means that both the assertion and reason are correct and the reason is the correct explanation for the assertion.
