• Explain why animal cells do not require a cell wall or a central vacuole.
short answer
Animal cells do not require a cell wall or a central vacuole because they gain structural support from their extracellular matrix, which is a network of proteins and other molecules surrounding the cells. This extracellular matrix provides a flexible and dynamic support system that can adapt to changes in the cell's environment.
Additionally, animal cells do not need a central vacuole because they have many small vacuoles scattered throughout the cytoplasm. These small vacuoles perform various functions such as storing nutrients, regulating water balance, and facilitating waste removal. Therefore, animals cells do not need a large central vacuole like plant cells, which primarily functions to maintain turgor pressure and store water.
