Question

The structure that helps locomotion in prokaryotic cell is

• A. Cilia
• B. Flagella
  
• C. Pseudopodia
• D. Both B and C
  

Answer 1

Answer: (D)

Both B and C

Flagella is the organ of locomotion in bacteria. They are made up of the protein flagellin and helical in shape. The flagellum rotates in a clockwise or counterclockwise manner like a propeller facilitating locomotion.

Pseudopodia, also called false feet are temporary extensions of the cytoplasm-filled cell membrane used in locomotion and feeding.

Thus the correct answer is option D.
