These protists are mostly unicellular (a few are colonial) organisms with spherical or elongated bodies with a single central nucleus. They possess one to many long, whip-like flagella that enable them to move. Flagellates move rapidly, pulling themselves forward by lashing flexible flagella, that are usually located at the anterior end. Examples include Trypanosome, Euglena, etc. The above lines indicate which of the following groups of protozoa:

Explanation

Zooflagellates are mostly unicellular (a few are colonial) organisms with spherical or elongated bodies with a single central nucleus. They possess one to many long, whip-like flagella that enable them to move. Flagellates move rapidly, pulling themselves forward by lashing flexible flagella, which are usually located at the anterior end. Flagellates obtain their food either by ingesting living or dead organisms or by absorbing nutrients from dead or decomposing organic matter. They may be free-living, symbionts or parasites. Trichonymphas are complex, specialised flagellates with many flagella which live as symbionts in the guts of termites and help in the digestion of dry wood
