In amoeba, digestion occurs through phagocytosis, where food particles are engulfed by the cell membrane and enclosed in a food vacuole. The food is then broken down by enzymes within the vacuole. In a mouse, digestion is a more complex process that involves different organs such as the mouth, stomach, and intestines. The food is broken down mechanically by chewing and then chemically by enzymes and acids in the stomach and small intestine. The nutrients are then absorbed into the bloodstream and transported to cells throughout the body.
In three to five sentences, compare the process of digesting food in an amoeba and mouse
The digestion process in an amoeba occurs within its single cell. It engulfs food particles by extending its cell membrane around them, forming a food vacuole. Then, enzymes break down the food inside the vacuole, and nutrients are absorbed into the cytoplasm. In contrast, a mouse has specialized organs involved in digestion. It chews food with its teeth, breaking it down before swallowing. The food then enters the stomach where enzymes and stomach acid break it down further, facilitating nutrient absorption in the small intestine.
In an amoeba, the process of digesting food begins with engulfing the food particle using pseudopods to form a food vacuole. Various enzymes are then secreted into the vacuole to break down the food into simpler molecules, which are finally absorbed directly into the cytoplasm. In contrast, in a mouse, digestion starts with chewing and swallowing the food. It then travels through the esophagus and stomach, where digestive enzymes and acid break it down further. The resulting nutrients are absorbed in the small intestine and then transported to different cells in the body for energy and growth.
