Animal cells do not have cell walls<span> because they </span>do not need<span> them. </span>Cell walls<span>, which are found in </span>plant cells<span>, maintain </span>cell<span> shape, almost as if each </span>cell has<span>its own exoskeleton. This rigidity allows </span>plants<span> to stand upright without the </span>need<span> for bones or musculature.</span>
