How do roots absorb water instead of presence of waxy - material suberin in the form of casparian strips on the wall of endodermis?
The plants do  have waxy walls and stuff, the plants use "Suction Method" to suck the water from the ground. Due to transpiration plants loose water from the top or aerial region of the plant and since water is absent in that region there is vacuum present so it sucks water from the ground. This is how plants absorb water.
