Which of the following is correct for the given structure?
Correct answer: D. All of the above
- A. These are small structures which work like oars
- B. It is covered with plasma membrane
- C. It's core is called axoneme
- D. All of the above
Explanation
Cilia and flagella are hair-like outgrowths of the cell membrane. Cilia are small structures working like oars, causing the movement of either the cell or the surrounding fluid. Flagella, in comparison, is longer and is responsible for cell movement. Both cilium and flagellum are covered with plasma membrane. Their core, called axoneme, possesses a number of microtubules running parallel to the long axis.So, the correct answer is 'All of the above'.
