Cactus are unique plants, but what makes them so special? While some have been documented to live for hundreds of years, others have become an awe thanks to their bizarre growth patterns, unique shapes and unmatched resistance to harsh conditions. Is Cactus A Succulent? What is the difference between cacti and succulents? Because regular leaves don't conserve water well, the cactus developed these modified leaves to adapt to its extremely dry environment.

The spines are better at conserving water and surviving in hot temperatures. Regular leaves provide a large surface area for evaporation of water to occur, the tiny spines do not. The spines actually collect moisture from the air and let it drip down to the roots of the cactus. Also, spines are used to ward off predators.

Would you want to eat something that is prickly? Then, when the air cools down at night, the internal heat slowly radiates back out but keeps the tissue from freezing on cold winter nights. Most cactus stems have a pleated surface. They may be covered with protuberances known as tubercles , or the tubercles may be lined up and fused together to form ribs. Tubercles are actually modified leaf bases called podaria, and each podarium has its own cluster of spines. The stems of cacti often have a waxy coating, or cuticle, that helps retain moisture inside the plant.

The cuticle covering cactus stems is waterproof and very thick compared to the outer skin of other plants. Desert cacti have shapes, or what botanists call growth habits, that are very different from anything else in the plant world, and they can be pretty odd looking! Without leaves serving as factories for plant growth, desert cacti have less green tissue conducting photosynthesis.

As a result, they are slow growers. A slow metabolism is one of the most essential cactus adaptations for surviving in the desert, where conditions are difficult and uncertain, for several reasons:. Learn more about the growth rate of cacti here. In addition to their odd growth habits and lack of leaves, another one of the remarkable cactus adaptations is their spines. All cacti produce spines, although a few types only have them when they are young. These spines come in many shapes and sizes.

They can be long or short, stout and spiky or fine and hair-like, bristly, woolly, needle-like, barbed, hooked, straight, or curved. And they vary in color. But cactus spines could hardly be more different from regular leaves — not only in appearance but also in function and makeup, since spines consist of hard fibers made largely of dead cells, as opposed to the living cells in green leaves that generate food for the plant through photosynthesis.

One rather obvious function of cactus spines is to protect the plant from predators. This may seem like overkill, but this level of protection is essential for cactus survival. Protection from predators, however, is not the only way cactus spines help the plant survive in harsh growing conditions.

Surprisingly, cactus spines actually play several very important roles in helping the plant conserve water and protect itself from the harsh effects of the sun — and they even help collect moisture, too! However, there are a couple of ways that spines can be quite effective as a protective sunblock:. Another interesting way that spines help cacti survive desert environments is by regulating the airflow around the plant.

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.

Perhaps the most surprising way that spines help cacti survive in the desert is by collecting moisture for the plant. Fibre to Fabric 4. Sorting Materials into Groups 5. Separation of Substances 6.
