Cactus root system is very developed, not only can go deep into the ground, but also can spread to the surrounding growth. The roots of some varieties can grow up to tens of meters long and go deep into the ground to get groundwater. In addition, its root system is relatively strong, and it is also very firm, which can ensure that it will not be unable to absorb water due to root problems.
Its leaves are needle shaped, which is due to its degradation 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.
Its stem surface has a layer of wax, which can protect it from dehydration caused by strong sunlight. In addition, this layer of wax can also slow down the evaporation of water in the plant and help it resist drought.
