Question

Unlike the cells of plants and fungi, animal cells lack what?

Answer 1

cell wall

Like the cells of all eukaryotes, animal cells have a nucleus and other membrane-bound organelles  see Figure below  . Unlike the cells of plants and fungi, animal cells lack a cell wall. This gives animal cells flexibility. It lets them take on different shapes so they can become specialized to do particular jobs. The human nerve cell shown in Figure below is a good example. Its shape suits its function of transmitting nerve impulses over long distances. A nerve cell would be unable to take this shape if it were surrounded by a rigid cell wall.
