AMOEBAS
Amoebas are easier to describe. You may have even seen these in your classrooms. They are small-single celled organisms that ooze from place to place. They reach out with one part of the cell, a structure called a pseudopod.
Amoeba genus name for one-celled organisms which have pseudopodia and belong to Kingdom Protista; Division Rhizopoda

Entamoeba histolytica
Entamoeba histolytica, another water-borne pathogen, can cause diarrhea or a more serious invasive liver abscess. When in contact with human cells, these amebae are cytotoxic.
Entamoeba histolytica. Causes amebic dysentery, the third most common parasitic disease of humans (after malaria and schistosomiasis).

myxamoeba - in Dictyostelium discoideum, the solitary haploid cell of the vegetative life cycle that lives on bacteria and reproduces by binary fission until the food supply is exhausted.
Amoeba make use of contractile vacuoles to collect excretory waste, such as ammonia, from the intracellular fluid by both diffusion and active transport.
Amoeba moves by extensions of their cytoplasm known as pseudopodia. Pseudopodia, shown in Figure 18, are used by many cells, and are not fixed structures like flagella but rather are associated with actin near the moving edge of the cytoplasm.

In many school science labs, children observe amoebas under the microscope and watch the single-celled organisms eat by stretching out pseudopodia and encircling any food particles they find in their paths.
Not just bacteria and viruses, but amoeba and all sorts of unusual things that are not supposed to get in our body and cause disease. So along comes the AIDS virus. Have we faced a virus like that?
Eukaryotes include protists (single celled organisms like amoebas and diatoms and a few multicellular forms such as kelp), fungi (including mushrooms and yeast), plants and animals.

amoeboid movement A form of movement similar to that found in amoebae. Fluid endoplasm (plasmasol) flows forward inside the cell and changes state to viscous ectoplasm (plasmagel) on reaching the tip of a pseudopodium.
Pseudopodia are temporary extensions of the plasma membrane used for movement or to engulf particles. Pseudopodia can be seen in the Amoeba below.
Cell Wall
