NEET BIOLOGY

Detailed explanation-1: -Answer and Explanation: The function of the cilia and flagella in the protists is to provide movement for the organism. Looking at cilia, these tiny, hair-like structures that provide movement through water environments.

Detailed explanation-2: -Some animal-like protists move by using cilia. Cilia are hair-like projections that move with a wave-like pattern. The cilia move like tiny oars to sweep food toward the organism or to move the organism through water. An example of these is the paramecium.

Detailed explanation-3: -c) Ciliary locomotion-Cilia are hairlike projections and cover all the body surface. They work coordinately by beating movements and helps the protists to move.

Detailed explanation-4: -A few forms can move by gliding or floating, although the vast majority move by means of “whips” or small “hairs” known as flagella or cilia, respectively. (Those organelles give their names to informal groups-flagellates and ciliates-of protists.) A lesser number of protists employ pseudopodia.

Detailed explanation-5: -Ciliates are an important group of protists, common almost anywhere there is water-in lakes, ponds, oceans, rivers, and soils. About 4, 500 unique free-living species have been described, and the potential number of extant species is estimated at 27, 000–40, 000.
