Stems that can store water
. Widespread or very deep root systems that can collect water from a large area or from very deep underground.
What adaptation helps a cactus survive in its environment?
A cactus is able to survive in the desert due to the following features: (i)
It has long roots that go deep inside the soil for absorbing water
. (ii) Its leaves are in the form of spines to prevent water loss through transpiration. (iii) Its stem is covered with a thick waxy layer to retain water.
What are the behavioral adaptations of a cactus?

unique inner cell structures and features on their outer surfaces to store and preserve water
.
