NEET BIOLOGY

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.

Detailed explanation-2: -Cilia are short projections that look like hairs. They move back and forth, similar to the motion of the oars of a rowboat. Flagella are longer, whiplike projections that propel cells. Both cilia and flagella are composed of microtubules.

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: -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.

Detailed explanation-5: -Cilia: These are hair-like projections that are present in eukaryotic cells that assist in movement, locomotion, as well as sensation. Ciliary movement: This involves the synchronised movement of the cilia in order to bring about its functions.
