D) microvilli.
E) nucleoli.

Question

Quizplus · Accepted Answer

Cilia are projections from the surface of cells found in abundance in the respiratory tract. They are responsible for moving mucus and other substances out of the airways. Flagella are similar structures found on some cells, but they are typically longer and fewer in number. Centrioles are important for cell division, while microvilli are tiny projections that increase the surface area of the cell. Nucleoli are small structures within the nucleus that are involved in making ribosomes.
