This means less water is lost to the atmosphere through evaporation. Spines grow from specialized structures called areoles, and defend the cactus from water-seeking animals. Cactuses have many adaptions to survive in dry, hot regions. Bamboo has very little nutritional value, so to conserve energy pandas move slowly, even though they are capable of moving very fast. The collected dew liquified into water and drips to the ground below. The adaptations of barrel cactus are by far the most fascinating adaptations seen in plants. They also form Arbuscular Mycorrhiza that allows the plant to get the nutrients and minerals from the soil that they need to help them grow. The saguaro is consists of a taproot system which runs about three feet into the ground and is used to collect deep ground water and nutrients as well as help anchor the saguaro.

The problem for plants trying to survive in hot, arid climates, where water evaporates quickly, is that when their stomata open to facilitate photosynthesis, water vapor escapes. If you think about it, it makes sense for plants that need to store water for survival to grow in shapes that provide the highest possible internal volume while minimizing the surface area thats exposed to the hot sun. This adaptation is what gives them their main characteristics. Other desert adaptations shared by a number of plants include shallow widespread roots to absorb a maximum of rainfall moisture and spines or hairs to shade plants and break up drying winds across the leaf surface. During the day, heat absorbed into the plants tissue brings the internal temperature up a bit, but the waters thermal inertia keeps it from rising as high as the lethal external temperatures that can occur in the desert. These adaptive traits are all physical adaptations. A brief of these adaptations are as follows: If you could take a closer look at a cactus, it does not have any structures resembling leaves.

One of the most striking cactus adaptations is their lack of leaves. The Saguaro cactus has a lifespan of between 100-200 years and can weigh between 2 to 3 tons at maturity. 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. It is found in the dry areas of the Mojave, Chihuahua, and the Sonoran deserts. Behavioral adaptions are characteristics of animals which being capable of conscious movement, can behave meaningfully.
