Explain why animal cells do not require a cell wall or a central vacuole

Answer 1

Animal cells do not require a cell wall or a central vacuole because they are surrounded by a flexible membrane that is composed of lipids and proteins. This membrane is able to change shape and size to accommodate the needs of the cell. The membrane also provides protection from the environment and helps to regulate the movement of molecules in and out of the cell. The central vacuole is not necessary because animal cells lack the rigid cell wall that is found in plant cells. This cell wall provides structural support and helps to regulate the movement of molecules in and out of the cell. Without the cell wall, animal cells rely on the flexibility of their membrane to provide protection and regulate the movement of molecules.

Answer 2

So that plant cells can move their leaves to get more sunlight, they have cell walls. But animal cells have skeletons so they don't need the support and structure provided by cell walls. Animals may have some small vacuoles but plants have one large vacuole in order to store the food made in photosynthesis.
