The barrel-shaped stem of this plant actually works as a water reservoir. Areoles are a distinguishing feature of a cactus plant, meaning that if a plant has areoles, it must be a cactus and if it doesn’t have areoles, it can’t be a cactus. Cactus tubercles and ribs play an important role in water storage and retention, as they allow the stem to expand to increase the volume of moisture it can hold without stretching or bruising and then retract as the stem loses water, which minimizes the amount of surface area that’s exposed to direct sunlight.

These cacti produce flowers that tend to open in the evening and at night, are less brightly colored than is typical of other cactus flowers, exude a musty smell, and produce a large amount of sugary nectar. Barrel cactus, name for a group of more or less barrel-shaped cacti (family Cactaceae) native to North and South America. So spines are modified leaves, and they grow out of organs called areoles that are modified branches. Like the other members of cacti family, even this species has some of the most amazing adaptations to its credit. If it were not for them, it would not have been possible for this species to survive the harsh conditions of the North American deserts. They open up to take in carbon dioxide and give off oxygen during photosynthesis and close when there’s insufficient sunlight. It has an average lifespan of 50 to 100 years, though some plants are known to survive for as long as 130 years. Additionally, in many types of cacti, these special cortical cell walls are undulating rather than smooth, so the cells can collapse in on themselves and release the water more efficiently. The most common species in California, Ferocactus cylindraceus, has yellow petals that are reddish at the base. We'll assume you're ok with this, but you can opt-out if you wish. Cacti have numerous anatomical and behavioral adaptations for absorbing and storing water, preventing water loss, protecting themselves from predators, limiting damage from the hot sun, saving their energy, requiring few resources, and attracting pollinators. By breaking up the airflow, spines create a layer of air – or what could be called a microclimate – that serves as insulation against changes in temperature as well as accelerated evaporation brought on by hot air or wind. The cuticle covering cactus stems is waterproof and very thick compared to the outer skin of other plants. Cacti also have thicker cortical layers than any other plants. In fact, there are different types of cactus spines, and some of them don’t have a deterrent function at all. Well, we're looking for good writers who want to spread the word. The water storing chamber in this plant has the greatest volume to surface ratio in plants. The dense spines, which are designed to protect the plant from heat and animals, facilitate water retention by ensuring minimalistic loss of water in the dry environment. Tubercles are actually modified leaf bases called podaria, and each podarium has its own cluster of spines. Pictured above is the mother-in-law's cushion or golden barrel … It’s because of the process of photosynthesis and the requirement of having pores to take in carbon dioxide and give off oxygen that cacti dropped the need for leaves. And they vary in color. (Causes & Solutions), How To Care For Kentia Palm (Howea Forsteriana), the cortical layer of cacti is unique among plants. Over the years, species like barrel cactus have modified themselves to fit into the dry desert biome with immense ease. These root hairs grow quickly, rapidly increasing the surface area of the root system that’s in contact with the soil. It doesn’t have leaves, so the stem facilitates the process of photosynthesis. As a result, they are slow growers. These spines come in many shapes and sizes. Perhaps the most surprising way that spines help cacti survive in the desert is by collecting moisture for the plant. Bat pollination is not very common among flowering plants. One rather obvious function of cactus spines is to protect the plant from predators.

Would you like to write for us? The focus of this article will be desert cacti and the different ways they have adapted to hot, arid environments. I hope you have enjoyed this look into the amazing cactus adaptations that help these plants survive in desert environments. These animals and birds feed on them and indirectly help in dispersing its seeds, thus facilitating reproduction of this species. Learn more about why cacti have spines here. And the reason for this change is, once again, to minimize the loss of moisture through stomata. These water-storage cells in the stems of cacti are filled with mucilage, the gooey substance found in many succulent plants that is very good at binding water and preventing it from evaporating.
