               Other protozoa have flagella, or
               tails, that assist in feeding.  The
               flagella whip back and forth
               creating a current that brings food                Figure 17 – The use of cilia (left) or a false

               Animal-like protists can be                        Plant-Like Protists
               classified, or placed into groups,
               based on how they move.  As                        Plant-like protists are similar to
               mentioned above, some move with                    plants because they are

               structures called cilia which they

               a “fake foot” or pseudopodia.                      soil and on the outside of plants.

               These protozoa have a part of their
               cell stretch out, which pulls the
               rest of the organism along.
