Since animal cells lack a rigid cell wall it allows them to develop a great diversity of cell types, tissues, and organs.Most cells are covered by a protective membrane known as the cell wall which gives the cells their shape and rigidity.The cells that constitute an animal are called Animal cells and those that constitute plants are known as plant cells.
