Question

Quizplus · Accepted Answer

Cilia are slender, hair-like structures that extend from the surface of a cell and function in moving substances across the surface of the cell. They are found in many different types of cells throughout the body, including the respiratory tract, where they help to move mucus and debris out of the lungs.

Answer: C
 Microvilli are also hair-like processes that extend from the surface of a cell, but they are shorter and more numerous than cilia. They are found on the surface of cells that line the intestines and other organs involved in absorption and secretion, where they increase the surface area for these processes. However, they do not function in moving substances across the surface of the cell like cilia do.

Therefore, the best answer is A.
