sahara desert plants details

Desert plants are not necessarily sun lovers. They are non-mobile organisms that cannot hop in a car to cooler climes. Desert plants are especially adapted to living in this arid climate. Many have small leaves with waxy coverings to minimize moisture loss, while cacti store large volumes of water. Desert plants are expert survivors. One characteristic of desert plants that people always notice is their survival adaptations.

Desert plants are uniquely adapted to life in a harsh and sometimes extreme environment. They often look unusual, and are sometimes quite beautiful. Desert plants are adapted to a hot dry sunny climate whereas plants in northern New England are adapted to survive hot sunny summers as well as freezing snowy winters. Adaptations include thick waxy leaves to reduce moisture loss or dropping leaves and entering a state of dormancy to survive freezing temperatures. Desert Plants are perfect for creating a natural-looking planted habitat for terrarium-dwelling animals. Animals will use them for climbing, hiding places and to lap up water droplets when misting.

Desert plants are best gown nearby any river. Every soil needs nitrogen for the growth of the plants. Desert plants are known for their interesting shapes, colorful flowers, and wonderful textures. For people living in areas outside the desert, there are ways to grow desert plants in gardens, greenhouses, and on windowsills. Desert plants are often very slow to grow, and this is one of the reasons they invest so much energy in defensive structures (spines) and chemicals - they can't afford to lose such hard-earned biomass.

Hot and Dry Deserts usually have very little rainfall and/or concentrated rainfall in short periods between long rainless periods. This averages out to under 15 cm a year. Hot air rising over the equator flows northward and southward; the currents cool in the upper regions and descend as high-pressure areas in two subtropical zones. North and south of these zones are two more areas of ascending air and low pressure. Hot deserts are such like the Sahara desert in North Africa where there is little rainfall for an entire year. Cold deserts is where precipitation (rainfall) is mainly snow - but only ten inches or less per year such as the Great Bain are in the United States or the Gobi desert in Northern China.

Adaptations to lose heat include high surface-to-volume ratios and long appendages (ears, legs). Some aquatic invertebrates persist in the same way as do annual plants, with dormant stages in their life history that are stimulated to develop by occasional sufficient rainfall. Adaptations include secreting a waxy substance to protect their leaves from drying out, thorns and spines to keep hungry animals at bay, and body shapes that can expand rapidly when water becomes available. Plants have large networks of roots that lie near the surface and can capture rain when it falls. Adaptations to deter herbivory are also conspicuous among desert succulents, which can tolerate little biomass loss as a result of their intrinsically slow growth rates. Common modifications include the production of physical deterrents; i.e., thorns, spines, prickles; however, some desert plants produce toxic secondary metabolites that presumably serve a similar function.

Cactus spines are modified leaves that protect the plant from being eaten and serve to break up the sun's rays. Pleated ribs also provide shade for 50 percent of the stem's surface area. Cactus wren frequent areas with thorny shrubs, cacti and trees and forage mostly on the ground around vegetation for insects, such as beetles, ants, wasps and grasshoppers, and occasionally lizards or small frogs. Some cactus fruit and berries and seeds are also eaten. Cactus fruits, such as saguaro and prickly pear fruits, are edible and also can be used to make jelly and candy. In addition, botanicals like jojoba, Mormon tea, desert broom, Mexican mint marigold, desert lavender and mesquite also have healing qualities that soothe, calm and cure when brewed into teas or made into poultices (mixtures of healing herbs that are heated, spread on a cloth and applied to the body).

Roots can be 5 times bigger than the parts of the plant above ground that you can see. The fungal partner can be quit a bit bigger. Roots have the dual functions of bringing water and dissolved minerals from the soil into the plant body to be distributed as needed. There are two major root types: tap and fibrous. Roots will form at the break sites on the veins. Then the roots will send up small new shoots.

Agaves and Yuccas are unique plants that are leaf succulents. They store large amounts of water in their leaves, making them very well adapted to our Sonoran Desert climate. Agaves are a diverse genus of over 200 species of rosette, spear-like, leafed evergreen perennials. Agave typically grows as low shrub-like plants in dry or well-drained soils of the Southern part of the U.S.
