Quizplus · Accepted Answer

The primary cilium lacks a central pair of microtubules, is not found in blood cells, and functions in the kidney to monitor urine flow. Microvilli are small, finger-like projections found on the surface of certain cells. Cilia are cell extensions that are longer than microvilli and have a central pair of microtubules. Flagella are whip-like structures used for movement, such as the tail of a sperm cell.
