The protozoa you will observe today is called the amoeba. An amoeba is unicellular and moves by using pseudopods. A pseudopod is a temporary bulge that forms in the cell membrane as a result of the movement of the cytoplasm.The word pseduopod means false foot.. The pseudopod has two functions, or uses: 1. to move, 2. to capture food.Note: in the picture the cytoplasm is called the plasmasol and the cell membrane is called the plasma membrane.) Because the amoeba uses pseudopods to move and capture food, it is classified as a sarcodine. A sarcodine is a protozoan that uses pseudopods. Example of a pseudopod in an amoeba.
