Why does a cactus have thick stem?
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.

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.

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.
