This AP biology type question requires you to distinguish between multicellular organism systems like our excretory systems(sweat glands, urninary system, large intestine), our digestive system (mouth, teeth, tongue, esophagus, stomach, small intestines, large intestines), the respiratory system (nostrils, sinus cavity, epiglottis, trachea, bronchioles, lungs, alveoli, red blood cells, hemoglobin, left atria, left ventricle, aorta and on to the cell for delivery of the oxygen). On the other hand, the amoeba is single celled. Lysosomes digest food. It gets its food by capturing using pseudopods and then endocytosis. Waste is removed with vesicles fusing with the cell membrane through exocytosis. All growth occurs through protein production and vesicle membrane fusing with the cell membrane. This would probably be a 2 paragraph answer and you would have about 23 minutes to answer it.
