Actually, cell walls are found in both prokaryotes and eukaryotes. In plants (eukaryotic) the cell walls are composed of cellulose whereas in prokaryotes, the cell walls are composed of peptidoglycan.
Animal cells are typical of the eukaryotic cell, enclosed by a plasma membrane and containing a membrane-bound nucleus and organelles.Unlike the eukaryotic cells of plants and fungi, animal cells do not have a cell wall.This feature was lost in the distant past by the single-celled organisms that gave rise to the kingdom Animalia.n prokaryotes, the membrane is the inner layer of protection surrounded by a rigid cell wall. Eukaryotic animal cells have only the membrane to contain and protect their contents. These membranes also regulate the passage of molecules in and out of the cells.
