Cilia vs. Microvilli: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Updated on October 16, 2023
Cilia are hair-like structures that move to propel cells or move fluids, while microvilli are finger-like projections that increase surface area for absorption.

Key Differences

Cilia are slender, hair-like structures present on the surface of all mammalian cells. Microvilli, on the other hand, are tiny finger-like projections that can be found on the surface of certain cells, particularly those in the intestines.

The primary function of cilia is movement. They can either move cells or help move fluids over cellular surfaces. In contrast, microvilli do not aid in movement but play a vital role in increasing the cell's surface area, aiding in absorption.

Cilia are often longer than microvilli and can be found individually or in larger groups on cells. Microvilli, however, are typically found in large numbers, creating a brush-like border, especially evident on intestinal cells.

Structurally, cilia are complex and contain microtubules that aid in their movement function. Microvilli are simpler in structure, primarily consisting of actin filaments that maintain their shape.

Both cilia and microvilli are essential for the functioning of various cells. While cilia play a key role in the respiratory system by moving mucus and trapped particles, microvilli are indispensable for nutrient absorption in the digestive system.
