GENERAL HISTOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -Eukaryotic cilia and flagella are hair-like cellular appendages composed of specialised microtubules and covered by a specialised extension of the cellular membrane. Their structure, genes, proteins and functions are highly conserved throughout evolution from protists to humans.

Detailed explanation-3: -Cilia and flagella are antenna-like protrusions present on many types of eukaryotic cells. Consequently, they have evolved to perform diverse functions, such as locomotion, mucus clearance, fluid circulation, chemosensation, and mechanosensation.
