When a human digests food, it would use specialized cells in the digestive system such as stomach lining cells, intestinal cells, and pancreatic cells. These cells work together to break down the food into smaller molecules that can be absorbed and utilized by the body.
When an amoeba or other single-celled organism digests food, it would use its cell membrane to engulf the food particles and form a food vacuole. The enzymes within the vacuole then break down the food into simpler molecules that can be absorbed by the cell.
When a multicellular organism, like a human, digests food it goes through a process involving mechanical digestion (chewing), chemical digestion (enzymes breaking down food molecules), absorption of nutrients, and elimination of waste.
When a bacterial cell or other unicellular organism digests food, it does not require complex organs or specialized cells. Instead, the cell can directly absorb nutrients from its environment through processes like diffusion or active transport. The digestion process is simpler and more direct compared to the multicellular organism.
Discuss how a multicellular organism would use specialized cells to digest food, whereas the unicellular organism would not.
**Think about how a human eats a bowl of spaghetti and digests it. Now compare that to how an amoeba or bacterial cell would digest "food". How are the two processes different?**
