summarize this: 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.

Animal cells have a flexible cell membrane that acts as a protective barrier and regulates the movement of substances in and out of the cell. They do not have a cell wall for structural support, but instead have multiple small vacuoles that serve various specialized functions such as storing and transporting molecules, maintaining cell shape, and providing support to organelles.
