The process of digesting food in an amoeba is relatively simple compared to multicellular organisms. The amoeba utilizes phagocytosis to engulf food particles, forming a food vacuole. The vacuole then fuses with lysosomes, which contain digestive enzymes, to initiate the breakdown of food. The nutrients released from digestion are absorbed by the amoeba's cell membrane, while undigested waste is expelled through exocytosis. In contrast, multicellular organisms have a more complex digestive system involving specialized organs such as the stomach and intestines to break down and absorb nutrients efficiently.
Amoebas are unicellular organisms that obtain nutrients through a process called phagocytosis. When an amoeba encounters a food particle, it extends its pseudopods around the food and engulfs it, forming a food vacuole. Digestive enzymes are then secreted into the vacuole, breaking down the food into smaller molecules. These molecules are absorbed by the amoeba's cell membrane, providing it with energy for growth and survival. In contrast, multicellular organisms have specialized organs and systems, such as the gastrointestinal tract, to digest food.
