Question

In three to five sentences, compare the process of digesting food in an amoeba (unicellular) to those in a mouse (multicellular) .(4 points)

Answer 1

In an amoeba, digestion occurs through a process called phagocytosis, where the organism surrounds its food with pseudopodia, forming a food vacuole that merges with lysosomes for enzymatic breakdown. This unicellular organism directly absorbs the nutrients into the cytoplasm for energy and growth. In contrast, a mouse, as a multicellular organism, uses a complex digestive system involving specialized organs such as the stomach and intestines, where food is mechanically and chemically broken down, allowing for nutrient absorption into the bloodstream. This multicellular approach enables mice to process larger quantities of food and utilize it more efficiently for their energy needs.
