It is about 2 ft. tall. The roots which emerge from the sides of the stems are fleshy and are there to anchor the climbing cactus stems to the trees or rocks supporting the plant, Smooth Endoplasmic Reticulum: Structure, Functions and Diagram, Adventitious Root System: Types, Modifications and Examples, Freezing Point Depression Examples in Everyday life. The modified leaves of cacti also play a role in their ability to withstand desert conditions. Their roots and stems are the reason for their survival in the great drought conditions. Here’s where the cactus stores water. Cactus Roots Gather Water Quickly And Efficiently After Brief Desert Rains. The cactus plant survives in the desert by using the adaptation technique. Roots: Cactus roots help to gather and preserve water in several ways. Some Cactus grows in the soil while others either grow on other plants (epiphytes), rocks or on the trees. A taproot anchors a plant from washing away during storms and conducts deeper subsurfaces soil layers with more moisture. Instead, they have spiny needles which stick out of their stems.

Cactus in the wild grow up to 100 years while the Cactus grown indoors lives up to almost 10 years. If a cactus is not getting enough water through its roots in the soil, but the atmosphere is humid, aerial roots can start to grow in an effort to collect the water from the surrounding atmosphere.

Since the leaves of these plants are reduced to spines in order to decrease the surface area for the evaporation of water, the stems hold the responsibility for the photosynthesis.
