Detailed explanation-1: -Tiny hairlike organelles called cilia cover many cells from single-celled microorganisms to mammalian tissue. Motile cilia beat actively generating cilia-driven flows.
Detailed explanation-2: -Ciliates are microorganisms with small, hair-like projections on their surface called cilia. The cilia can be very numerous, covering the entire surface of many microbes, or several can be fused together to form a bundle. Cilia beat in a coordinated fashion to propel the organism through the water.
Detailed explanation-3: -What are cilia? Cilia are long, slender, hair-like projections found on nearly all of our cells. They are involved in a range of tasks, including cell proliferation, receiving sensory information, and communication between cells.
Detailed explanation-4: -Surface appendages or hairy structures present in some bacteria for attaching to one another are called as pili. Flagella is a whip-like structure present on some bacteria that allows in cell movement. Cilia are slender protuberances or hair-like projections that are present on the cell body of eukaryotes.
