Animal cells do not have cell walls since animals have other means of physical support, such as the skeleton. what would be the problem if animal cells have cell walls?

"Animal cells do have a little more variety because plant cells have rigid cell walls. This limits the shapes that they can have. Both plant cells and animal cells have flexible membranes, but these are inside walls in plant cells, sort of like a trash bag in a trash can. Animal cells just have the membrane."
