An amoeba is a single-celled organism that lacks a defined digestive system. Instead, it engulfs food particles using a process called phagocytosis. The food is enclosed in a membrane-bound vesicle called a food vacuole, which fuses with lysosomes, and digestive enzymes break down food molecules. The nutrients are then absorbed by diffusion across the cell membrane, and the waste material is eliminated through exocytosis. Overall, amoebas have a less efficient and less specialized digestive process compared to multicellular organisms.
The process of digesting food in an amoeba involves the engulfment of food particles through a process called phagocytosis. First, the amoeba extends its pseudopodia to encircle the food particle and forms a food vacuole around it. Enzymes are then secreted into the vacuole to break down the food into simpler molecules, which are then absorbed into the cytoplasm. Finally, the undigested waste is expelled from the amoeba through exocytosis. This process allows the amoeba to extract nutrients from its surroundings to sustain its energy needs.
The process of digesting food in an amoeba begins with the food being engulfed by the amoeba through a process called phagocytosis. Once inside the amoeba, the food is enclosed in a food vacuole. Enzymes are then secreted into the vacuole to break down the food into smaller molecules for absorption. Finally, the nutrients are absorbed into the cytoplasm of the amoeba for the release of energy and waste elimination.
