cilia definition and function
Cilia and Flagella Cilia and flagella are motile cellular appendages found in most microorganisms and animals, but not in higher plants. In multicellular organisms, cilia function to move a cell or group of cells or to help transport fluid or materials past them.The respiratory tract in humans is lined with cilia that keep inhaled dust, smog, and potentially harmful microorganisms from entering the lungs.n multicellular organisms, cilia function to move a cell or group of cells or to help transport fluid or materials past them.

A cilium (plural cilia) is an organelle found in eukaryotic cells. Cilia are slender protuberances that project from the much larger cell body. There are two types of cilia:1  motile cilia, which beat against fluid outside the cell. 2  non-motile, or primary cilia, which typically serve as sensory organelles.ilia are slender protuberances that project from the much larger cell body.
