The black widow spider is an invertebrate. Its skeleton system hangs outside its body.

bekas [8.4K]

This gives the leaf, a rigid structure. But when there is dehydration, this pressure decreases and the leaves loose their shape and wilt. There is absence of pressure from inner side of the cell wall.
