NEET BIOLOGY

Detailed explanation-1: -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.)

Detailed explanation-2: -The ciliates are a group of alveolates characterized by the presence of hair-like organelles called cilia, which are identical in structure to eukaryotic flagella, but are in general shorter and present in much larger numbers, with a different undulating pattern than flagella.

Detailed explanation-3: -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.

Detailed explanation-4: -The ciliates are protists that move by using cilia. Cilia are thin, very small tail-like projections that extend outward from the cell body. Cilia beat back and forth, moving the protist along. Paramecium has cilia that propel it. The sporozoans are protists that produce spores, such as the toxoplasma.

Detailed explanation-5: -A protist can have one, two, or more flagella. Cilia are tiny hairs covering a protist. Cilia are also used for movement, and work by using a sweeping motion.
