1、 Huge root system

The root system of cactus is very developed. It can not only go deep into the ground, but also spread and grow around. The roots of some varieties can grow to tens of meters long and go deep into the ground to obtain groundwater. In addition, its root system is relatively strong and firmly rooted, which can ensure that it will not be unable to absorb water due to root problems

2、 Needle leaf

Its leaves are needle shaped, which is formed by degradation in order to adapt to the living environment of water shortage for a long time. Needle shaped leaves have a small area, which can effectively reduce water evaporation and help plants retain more water

3、 Waxy stem

Its stem surface has a layer of wax, which can protect it from dehydration caused by strong light sunburn. In addition, this layer of wax can also slow down the evaporation of water in the plant and help it resist drought
