Amoeba are consumer in mode of nutrition. Whenever they senses some food, they push a part of their cytoplasm packed in cell membrane towards the food to cover it. This process is called pseupodia.
This pseupodia engulfs the food and performs phagocytosis or pinocytosis. This food is covered in a cell membrane inside the cytoplasm which is called the food vacoule or endosome. This then fuses with a lysosome to digest and then the excretory product is let off by the secondary vacoule.
That statement is false. Bacteria are single-celled organisms.
