Some cells are single, self-sustaining organisms, such as amoebas and bacteria. Other cells are part of multicellular organisms and cannot survive alone. Cell Tissues In multicellular organisms, cells depend on each other and are organized into tissues that perform a specific job. Organs & Or gan Systems These tissues are further organized into organs and organ systems that work together to keep an organism alive. food vacuole nucleus cytoplasm pseudopod food contractile vacuole cell membrane muscle cell amoeba paramecia bacteria muscle tissue organ (heart) circulatory system One-Celled Organism - Amoeba A one-celled organism, such as an amoeba, is able to perform all of its life functions by itself. To consume food, the amoeba surrounds the material with its flexible membrane, forming a food vacuole around it. The amoeba then pulls the food into the cell for digestion.
