The term SLIDE SIGHT can be solved by the 6-letter word AMOEBA. An AMOEBA is a single-celled organism that moves by extending and retracting pseudopods, or false feet. It is a type of protozoan, which are simple, single-celled organisms that lack a cell wall. Amoebas are found in freshwater, saltwater, and soil environments. They feed on bacteria and other small organisms, and reproduce by splitting in two.
