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

The process of digesting food in an amoeba is relatively simple. When it encounters a food particle, it engulfs it through phagocytosis, forming a food vacuole. Then, digestive enzymes are secreted into the vacuole, breaking down the food into smaller molecules that can be absorbed by the amoeba's cell membrane.

In contrast, the process of digestion in a mouse is much more complex. It starts in the mouth, where mechanical digestion occurs through chewing, and chemical digestion begins with the secretion of saliva containing enzymes. The food then travels to the stomach, where further mechanical and chemical digestion takes place. Finally, in the small intestine, digestive enzymes break down the food into small molecules that can be absorbed into the bloodstream.

Overall, while both amoebas and mice carry out the process of digestion, mice have evolved a more specialized and compartmentalized system for this purpose, incorporating various organs and enzymes throughout different stages of digestion.

Answer 2

The process of digesting food in an amoeba involves engulfing food particles through a process called phagocytosis. Once inside the amoeba's cell, the food is enclosed in a food vacuole where it is broken down by enzymes and nutrients are absorbed. In a mouse, the process of digestion is more complex and involves specialized organs such as the mouth, stomach, and intestines. Food is ingested and broken down by mechanical and chemical processes, then absorbed into the bloodstream for distribution to various organs and cells in the body.
