EVERYDAY SCIENCE

Detailed explanation-1: -Cilia and flagella. Cilia and flagella are motile, hair-like projections of the cell surface. They create currents in the surrounding fluid or movements of the cell to which they are attached, or both. There are two categories of cilia: single non-motile primary cilia and multiple motile cilia.

Detailed explanation-2: -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-3: -Cilia are short, numerous, hair-like projections that move in a wavelike motion. Some cell surfaces have cilia and flagella, which are structures that aid in locomotion or feeding.

Detailed explanation-4: -The bronchus in the lungs are lined with hair-like projections called cilia that move microbes and debris up and out of the airways.

Detailed explanation-5: -Flagella (singular = flagellum) are long, hair-like structures that extend from the plasma membrane and are used to move an entire cell, (for example, sperm, Euglena).
