Question

In three to five sentences, explain why animal cells do not require a cell wall or a central vacuole for their functions.(4 points)

Answer 1

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

Answer 2

Make it short

Answer 3

Animal cells have a flexible and dynamic cell membrane, which serves as a protective barrier and a gateway for nutrients and waste. Therefore, a cell wall is unnecessary for structural support. Additionally, animal cells have multiple small vacuoles that perform specialized functions, instead of a single large central vacuole like in plant cells. These small vacuoles store and transport molecules, maintain cell shape, and provide structural support to different organelles.

Answer 4

In an amoeba, the process of digestion involves engulfing food particles, forming a food vacuole, and breaking down these particles with lysosomal enzymes. The nutrients are then absorbed and utilized by the cell for energy and growth.

In a mouse, the process of digestion is more complex and involves various organs such as the mouth, stomach, small intestine, and large intestine. The food is mechanically broken down in the mouth and chemically digested in the stomach and small intestine with the help of digestive enzymes secreted by different organs. The nutrients are then absorbed by the small intestine and transported to various parts of the body through the bloodstream.
