Giant succulents desert areas

The American desert has a giant cactus, called saguaro, as high as 50 feet and weighs 6 tons . The outer shell of this giant tree is green, covered with resin wax, which makes it capable of holding water. Rain rarely occurs in the desert. Sometimes half of the year 's rainfall falls in the desert in just one night, saguaro knows how to take advantage of every drop of rain it receives to sustain life during prolonged dry days.

The cactus roots spread wide to catch rainwater as a net when water seeped into the arid ground. The roots constantly suck in deep underground water. A fairly heavy rain can provide the saguaro tree with enough water to survive for 4 years of drought.

However, if you encounter a heavy rain, lasting into a great flood, because there is no water-stopping system, saguaro cactus will continue to absorb water until it bursts.

With its branches crawling to all sides, the saguaro cactus was a heavy plant and easily collapsed because of its own weight without a sturdy frame. Hard cells form a solid frame in the trunk of the plant, which helps the plant stand firmly. So this giant tree has adapted well to the harsh environment of the desert
