The American desert region is home to a giant cactus known as saguaro, which can grow up to 50 feet tall and weigh as much as 6 tons. The exterior of this colossal plant is green and covered in a waxy coating, allowing it to retain water. Rainfall is extremely rare in the desert. Sometimes, half of the annual rainfall occurs in just one night, and the saguaro is adept at making the most of every drop to survive the prolonged dry spells.
The cactus’s roots spread wide to catch rainwater like a net as it seeps into the parched ground. These roots continuously draw moisture from deep underground. A decent rainfall can supply the saguaro with enough water to last through four years of drought.
However, in the event of heavy rains that lead to flooding, the saguaro cactus will continue to absorb water until it bursts due to the lack of a drainage system.
With its branches sprawling in all directions, the saguaro cactus is a heavy plant that can easily topple under its own weight if it lacks a sturdy framework. Rigid cells form a solid structure within the trunk, providing crucial support for the plant to stay upright. Thus, this giant has adapted remarkably well to the harsh conditions of the desert environment.
