Compare the process of digesting food in an amoeba (unicellular) to those in a mouse (multicellular) .(4 points)
1. Omamebas digest food through a process called phagocytosis, where they engulf food particles with their cell membrane and form a food vacuole inside the cell. In contrast, mice digest food through the mechanical and chemical breakdown of food in the stomach and intestines.
2. Amoebas rely on intracellular digestion to break down food particles inside the food vacuole through enzymes secreted by lysosomes. Mice, on the other hand, have specialized organs such as the stomach, pancreas, and intestines to digest and absorb nutrients from food.
3. Amoebas often digest smaller food particles, such as bacteria and algae, due to their smaller size and simpler digestive system. Mice, being multicellular organisms, can consume a variety of food types and have a more complex digestive system to break down different types of food sources.
4. Both amoebas and mice ultimately use the digested nutrients for energy production, growth, and maintenance of cellular functions. However, mice also have the ability to store excess nutrients in the form of fat for energy reserves, which is not a capability of amoebas.
