Plants need water to survive, which is an idea you're probably already pretty familiar with. But a cactus is known for being able to live with very, very little water!
Cactuses (sometimes also called "cacti") are a type of plant called a "succulent," and are best known for living in hot, dry places like the desert, where they do not get a lot of water. Cactuses do need some water to survive, but can get along with a lot less than most plants.
One reason cactuses can get along with less water is because they don't have leaves, so the water a cactus drinks does not evaporate as much as the water other plants drink. Additionally,cactuses have thick stalks which allow them to store water for a long time and roots that are good at finding and soaking up water even when its scarce!
Cacti are desert plants well adapted to living for a long time during long periods of drought. The roots of most cacti are deep and well spread out. Any rainfall is stored in cells able to expand, usually in the barrel shape of the stem, or in the fleshy leaves of the succulents. This ability to take on and store water, helps the plant survive through long periods of drought.
The barrel cactus survive long periods of drought by storing sparse rain water in stem cells. Other species of cacti also store water. Leaves have evolved into thin spikes and thorns to reduce water loss, which would occur with conventual broad-leaves.
The cactus has a number of structural adaptations that allow it to live in the harsh conditions of the desert. Many other plants lack these adaptations and cannot survive in a desert.
There is no such thing as a "Joshua Cactus." There is, however, the Joshua tree which is a tree-like yucca found mainly in the Mojave Desert. It can live for hundreds of years and some specimens as old as 1000 years have been found.
There are two types of cactus, columnar cactus and climbing cactus. Climbing cactus e.g dragon fruit plant.
A cactus can store water in its fleshy stem and this enables it to survive periods of drought.
The cactus has the ability to store water in its fleshy stem so it can survive long periods of drought.
Wherever it grows, the cactus functions as a conversation piece because of its unusual appearance, its drought tolerance, and its adaptability to indoor and outdoor environments.
As with any green plant, the cactus produces its own food through photosynthesis.

The stem of a cactus is typically thick and succulent, allowing it to store water during times of drought. This adaptation helps the cactus survive in arid environments by providing a reserve of water for times when it is scarce. Additionally, the stem is often covered in a waxy layer to reduce water loss through evaporation.
A cactus has roots just as do other plants. These roots absorb water from the soil when it is available and store water in their tissues for ties of drought.
the plants which grow in the drought region(region where very less water is available0 e.g., cactus, date palm, bryophyllum etc.,
Most cacti are able to store water in their stems for periods of drought.
