________ Increase Surface Area to Facilitate Absorption of Extracellular Materials

Question

________ increase surface area to facilitate absorption of extracellular materials.
A) Cilia
B) Microvilli
C) Flagella
D) Centrioles
E) Mitochondria

Accepted Answer

Microvilli are small, finger-like projections on the surface of certain cells, such as those in the small intestine. They increase the surface area of the cell, allowing for more efficient absorption of extracellular materials, such as nutrients. Cilia and flagella are also cellular projections but serve different functions, such as movement. Centrioles and mitochondria are organelles within the cell that perform different functions.
