MICROANATOMY

Detailed explanation-1: -Giardia is a protist that moves with flagella. They can be found in freshwater streams and lakes. People who drink water containing this protist may become sick. Plant-like protists are commonly called algae.

Detailed explanation-2: -(c) Euglena uses a whip-like tail called a flagellum to propel itself. Some protists can move toward or away from a stimulus, a movement referred to as taxis.

Detailed explanation-3: -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.
