The stem which is the thick part of the cactus plant stores food.:)
Cacti have a thick stem so that when water/nutrients are available they can be absorbed in mass amounts for storage for use for a long period of time
The stem of a cactus is able to store water during rainy periods for use during a drought.
In cactus the leaves are reduced to spines in order to prevent water loss through transpiration though the stomata.Besides,the stem is also covered by a waxy coating which prevents water loss.Thus,cactus requires very less amount of water in order to survive
Leaves provide extra surface area for water to evaporate out of the plant. In the arid desert, plants need all the water they can get.

Enlarged stems carry out photosynthesis and store water. Unlike many other succulents, the stem is the only part of a true cactus where this takes place. Much like many other plants that have waxy coatings on their leaves, Cacti often have a waxy coating on their stems to prevent water loss. This works by preventing water from spreading on the surface and allowing water to trickle down the stem to be absorbed by the roots and used for photosynthesis. Cacti have a thick, hard-walled, succulent stem - when it rains, water is stored in the stem. The stems are photosynthetic, green, and fleshy. The inside of the stem is either spongy or hollow (depending on the cactus). A thick, waxy coating keeps the water inside the cactus from evaporating.
A cactus that stores water in its stem is called a stem succulent. The stem has tissues that are capable storing large quantities of water. The stem also has a thick waterproof epidermis covered by a waxy cuticle that prevents loss of water due by evaporation. Examples of stem succulents - Cardon Cactus, Organ Pipe Cactus, Saguaro Cactus
An interesting fact about a cactus is that a cactus has a thick, juicy and swollen stem inside his body which helps it to store water and when it gets thirsty because of the extremely hot weather, he can drink the water anytime he wants.
cactus have a hollow stem. it is where they store water and food for survival
A cactus stores water in its stem.
Water is stored in tissue in the stem of the cactus.

A cactus stores most of its water in its stem or body
Water, dissolved nutrients, and byproductsof photosynthesis are stored in the cactus stem. The water and the dissolved nutrients are sent up into the stem from the cactus plant's roots. They're held in the stem until they can be used in the photosynthetic interaction with sunlight. From that interaction are made the energizing carbohydrates, starches and sugars that the cactus needs for such activities as flowering, fruiting, growing, reproducing, and responding to stresses and stressors.

Cactus get by in deserts because of following variations: It has a level green stem to store water and plan food by photosynthesis. The stem is likewise covered with a thick waxy layer, which assists with holding water. Its underlying foundations dive deep into the dirt for engrossing water. Passes on transform into spines to forestall loss of water.
