Animal cells do not require a cell wall or a central vacuole for their functions because they have evolved different mechanisms to support their structure and function.
Firstly, animal cells have a flexible plasma membrane that maintains the shape and structure of the cell. This allows animal cells to be relatively soft and flexible, enabling them to change shape and move easily. In contrast, plant cells have a rigid cell wall that provides structural support and protection, but also limits their ability to change shape.
Secondly, animal cells have specialized organelles such as the cytoskeleton, which helps maintain the shape of the cell and provides support for various cellular processes. The cytoskeleton is made up of protein filaments that can rearrange and move within the cell, allowing for dynamic changes in cell shape and movement.
Additionally, animal cells have smaller, scattered vacuoles throughout the cytoplasm rather than a central vacuole like plant cells. These smaller vacuoles serve various functions such as storage of nutrients, waste removal, and regulation of cell volume, but are not essential for the overall structure and function of the cell.
In summary, animal cells have evolved different mechanisms to support their structure and function without the need for a cell wall or a central vacuole. Their flexible plasma membrane, cytoskeleton, and specialized organelles play key roles in maintaining cell shape, structure, and function.
