* Cytoskeleton: This network of protein fibers provides the cell's internal framework, giving it shape and helping it to move and divide. It also acts as a "highway" for the transport of organelles and other molecules within the cell.
* Cell Membrane: This outer boundary of the cell is a flexible barrier that helps to maintain the cell's shape and protect it from its environment. It also regulates the movement of substances into and out of the cell.
While the cytoskeleton provides the internal structure, the cell membrane provides the external boundary and support, working together to maintain the overall integrity and shape of the animal cell.
