GENERAL HISTOLOGY

Detailed explanation-1: -A flagellum (Latin for whip) is a lash-like appendage that protrudes from the cell body of some protists (as well as some bacteria). Flagellates use from one to several flagella for locomotion and sometimes as feeding and sensory organelle.

Detailed explanation-2: -Zooflagellates are a third type of protists. They are animal-like and move by using flagella.

Detailed explanation-3: -Protists have three types of appendages for movement. As shown in Figure below, they may have flagella, cilia, or pseudopods (“false feet”). There may be one or more whip-like flagella. Cilia are similar to flagella, except they are shorter and there are more of them.

Detailed explanation-4: -(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-5: -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.)
