Why is the stem of cactus thick and green?

cactus 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.

Why are leaves modified to form spines in the cactus plant how then does the cactus plant make food?

The cactus adapted to its harsh environment by developing thick skin to slow the evaporation of water. The leaves changed in order to reduce the surface area that water could evaporate from and over time became defensive spines to protect itself from animals trying to get inside its thick skin for the moisture. The cactus makes its food, by having chlorophyll throughout the rest of plant. That is why the entire cactus is green.


How do cactus plants stop water loss?

Cactus plants stop water loss mainly by modified leaves and thick stems. They have leaves in the form of thorns, spines, quills, prongs, needles or bristles. Such modified leaves have smaller surfaces from which water can evaporate. Additionally, the stomata or breathing pores are found on the cactus stem instead of the typical herbaceous location of the leaf surface. The outer skin of the cactus stem is thick and thereby prevents the escape of the water supplies inside the interior tissue.
