Why do plant cells need a cell wall but animal cells do not

Cell walls are rigid which gives plants their shape. Animals have only cell membranes which allows animals to be flexible as animals are moving organisms. Plants, on the other hand, are sturdy and upright and are sessile organisms. Cell walls allow plants to grow upright as high as their maximum height and to be sturdy enough to survive harsh environments.

The basic thing is that plants need rigid structure to support them as well as to defend themselves whereas, animals do not possess any sort of cell wall since animals always move, they are not static in one particular place, therefore they need to be flexible and as a result of that cell walls are absent.
