Extremely high temperatures during the day and evening temperatures that often dip below freezing are only the beginning of problems for desert plant life.Scarce rainfall coupled with very dry air make it difficult for plants to obtain water needed for photosynthesis and create competition between animals and plants.
Needles are arguably the most important part of all cacti and are without a doubt the most obvious sign that a plant is in fact a succulent.
The reason needles are so vital to cactus survival is because they protect the plant's stem, where photosynthesis is performed and water is stored.
Many of the cacti in the Trichocereus genus, such as the Trichocereus Pachanoi, the Trichocereus Peruvianus, and the Trichocereus Terscheckii, more commonly known as the San Pedro Cactus, Peruvian Torch Cactus, and Cardon Grande Cactus respectively, have been ingested in ritual ceremonies for thousands of years in the Americas for a chemical they produce called mescaline.
Mescaline is a psychedelic which is also found strongly in the Lophophora Williamsii, or Peyote Cactus.
To prevent this, cacti open their stomata at night, when it is significantly colder and much less likely to evaporate.
“Their problem then is that, as the carbon dioxide cannot be turned into sugar in the dark, it has to be stored in the form of organic acids.The stem of a cactus acts as the plant's water storage system.Once water is drawn in through the roots, it can be stored in the stem for long periods of time, allowing the cactus to live through the long periods of drought and intense heat for which deserts are so well known.Inside, is a golden tangle of stamens—three thousand of them in the Suaharo flower (Hylander).Americans and Mexicans should be especially proud of this stunningly gorgeous plant, since the southwestern United States and Mexico are where the succulent family originated before it quickly spread as far north as Alberta and all the way south to the Straits of Magellan.Just as animals around the world have evolved to better survive in their environments, botanical life everywhere has also been forced to grow and adapt to their habitats.Every plant—from the smallest strain of seaweed to the tallest redwood—is the result of billions of years of competition for optimal growth conditions.While the needles of succulents often make the plants look hazardous, inhospitable, and sometimes just plain ugly, when they flower in the spring, they are some of the most beautiful plants on the planet.Many cacti flower only at night, closing up during the day because the flowers themselves are often very sensitive to the relentlessly bright rays of the sun.The cell sap of the succulent thus becomes more and more acidic as its night-storage acid batteries become fully charged” (Bellamy).When the sun rises, the plant once again closes its pores and begins taking in sunlight, which allows it to complete the process of photosynthesis by turning the stored acids into glucose, or sugar.
