Small,fingerlike projections of the plasma membrane that increase the surface area of the cell and make absorption more efficient are called
A) cilia
B) ion pumps
C) microvilli
D) flagella

Question

Quizplus · Accepted Answer

Microvilli are small, fingerlike projections found on the surface of certain cells, particularly in the small intestine and kidney. Microvilli greatly increase the surface area of the cell membrane, which in turn increases the efficiency of absorption and exchange of materials between the cell and its environment. Cilia are similar in shape to microvilli but are typically longer and fewer in number. Ion pumps are specialized proteins that transport ions across the cell membrane, while flagella are whip-like structures that are used for locomotion.
