8. The answer is B) A prokaryotic cell does not have nucleus and a eukaryotic cell does.
Prokaryotic cells lack membrane bound organelles such as nucleus where as eukaryotic cell possess membrane bound organelles.
9. The answer is D) The nucleoid
Due to the lack of membrane-bound organelles, prokaryotic DNA is found floating in the cytoplasm in a specific region, which is known as the nucleoid.
10. The answer is A) Flagellum.
Flagellum is a whip like structure which is rooted to the basal body. It helps the prokaryotic cells move.
11. The answer is B) Pilus (Pili).
This structure helps the bacteria to conjugate. Two bacteria comes in contact with each other and form a connecting tunnel called pilus. Then the genetic material is exchanged through this tunnel.
