These leaves grow in clumps at the end of the thick branches, giving the Joshua tree a barren appearance. Yucca plants are commonly found in many deserts, and they withstand hot sun and little water. This yucca variety is commonly grown as an ornamental plant in the southern U.
This desert plant has lower leaves that curved backward and upper leaves that are long and stiff, which taper to a sharp point. Like most plants that thrive in desert climates, this yucca variety grows in sandy soil and coastal dunes. The thick trunk grows to about 4 or 5 ft. Yucca desert plants also bloom with large clusters of white fragrant flowers. The golden barrel cactus looks like a large spherical spiked globe.
The round green cactus has yellow or white sharp spines, and the plant produces a crown of small yellow flowers. These hardy desert plants are a great addition to rock gardens or desert landscapes in full sun and hot, arid conditions.
Golden barrel cacti are slow growers that can live for up to 30 years. The globular, low-growing plant may eventually reach 3 ft. These cacti are rare in deserts due to habitat destruction; however, they are excellent specimen plants growing in yards. You can plant them in sandy, well-draining soil in your yard or grow in pots. As the scientific name of this desert plant suggests, this is a huge cactus. Pictures of desert terrain often show this tall cactus with its large arm-like branches curving upward.
The thick columnar stem stores moisture that allows this plant to survive the driest of conditions. These common desert plants found in the hot, barren landscapes of the southwest states and northern Mexico. The saguaro cactus is the largest of any cactus to grow in the desert biome. These flowering plants also bloom in the desert between April and June. Large white trumpet-like flowers attract pollinators such as honeybees and hummingbirds.
Although these cacti grow up to 52 ft. So, if you want to create a desert landscape in your yard, a saguaro cactus is an excellent choice. The organ pipe cactus lives up to its name because of the long tubular succulent stems that look like a pipe organ. These common desert plants grow up to 16 ft. Desert dwellers prized these plants due to their large tasty fruits. Some say that the delicious fruits from this plant taste better than watermelon. These drought-tolerant plants grow well in gardens that get full sun and little shade.
As with most succulent and cacti, plant them in well-draining, sandy soil. In their native habitat, the cacti are found in Arizona and Mexico in the Sonoran Desert. Brittlebush is one of the most common desert shrubs in the southern states and Mexico.
As its common name suggests, the brittlebush has stems that are stiff and easily break. This low-growing shrub helps brighten up desert landscape when it flowers. The experts then identified bacteria living in this soil. Most bacteria were types that help plants grow in different ways. Some of the bacteria produced plant-growth hormones.
A hormone is a chemical that signals cells, telling them when and how to develop, grow and die. Other bacteria in the soil can fight the germs that make plants sick. Salty soil, extreme heat or a lack of water — all can stress a plant. Plants alert their tissues by producing ethylene ETH-uh-leen gas. Plants make this hormone in a strange way. From the roots, ACC travels up a plant, where it will be converted into ethylene gas. But bacteria can interrupt that process by consuming the ACC.
When that happens, the plant never gets its own message to stop growing. If the stress got too bad — too little water, or very, very high temperatures — this nonstop growth would cause the plant to die.
It published its findings in the journal Microbial Ecology. Mesquite and creosote are both perennials. That means these shrubs live for many years. Other desert plants, including many wildflowers, are annuals. These plants live a single year. That leaves them just one chance to produce seeds before they die. Now imagine if every single one of those seeds germinated following a rainstorm. If a dry spell followed and all the little seedlings died, the plant would have failed to reproduce.
Indeed, if that happened to every plant of its kind, its species would go extinct. Geological Survey. Bettors sometimes hedge a bet. Imagine that a desert wildflower produces 1, seeds that all fall to the ground. The first year, only of the seeds germinate. The other seeds are its hedge.
They just lie and wait. If that first year is very rainy, the seeds might have a good shot at growing into flowers. Each in turn can produce more seeds. If the year is very dry, however, many, if not most, of the seeds that germinated will die.
None of these seeds, then, got to reproduce. But thanks to the hedge, the plant gets a second chance. It still has more seeds in the soil, each able to grow next year, the year after that or maybe a decade later. Whenever the rains come. Hedging has its risks.
The Yucca is native to the southwestern United States and northern Mexico and is cultivated for its fruit by the Pueblo Indian tribes. There are numerous types of yucca plants, such as yucca filamentosa or Adam's needle which has a clump of leaves about 30 inches tall with a large flower stalk in the middle. Agaves are known for their giant panicles of flowers, interesting shape, colors, and textures.
While you may be familiar with the blue agave native to Mexico , where agave nectar is sourced, there are at least 18 known agave types found in seven of the 50 states. The greatest diversity of this plant type is found in Arizona, home to 12 species.
Most agaves have rosettes made from succulent, rigid and hard leaves that have marginal teeth and a sharp terminal spine. When thinking of desert plants, the Saguaro cactus comes to many people's minds. This edible succulent is the state flower of Arizona and only grows about one inch per year. When in bloom, the Saguaro cactus sports large white flowers with yellow centers on the tips of its branches. The blooms open at night and close when the sun gets hot in the early afternoon.
Another popular cactus is the prickly pear. The skin of the prickly pear is covered in spines called glochids. Some people mistake the large flat pads as leaves when in fact, the pads are just small branches.
The prickly pear blooms in the spring and large yellow flowers make this cactus easy to spot. When mature, the red fruit of the prickly pear is harvested, and the juice is used in fruit smoothies and health drinks. Another common name for the barrel cactus is the compass cactus because Native Americans used to use these plants for navigation. These cacti are found in the southwest area of North America including the Sonoran, Mojave and Chihuahua deserts.
Barrel cacti thrive in desert washes, gravel covered slopes and under desert canyon walls. These globe-shaped cacti grow very slowly and can live up to years. They are a greenish color with reddish-orange spines and brilliant red, orange or yellow flowers that bloom between July and September.
If you visit the desert, you will find a diverse sampling of shrubs and trees including the following:. Juniper is the most common desert tree in the southwestern United States. Juniper tends to grow at higher elevations and is usually seen on mesas. Junipers typically grow to approximately 40 feet tall and thrive better when they can receive full sun. If grown too close together, Junipers will have stunted growth and not produce as many berries.
This medium-size round shrub grows in clumps throughout the Sonoran and Mohave dessert. It can also be found in interior valleys in Southern California and in the coastal chaparral. The United States, for example, is usually divided into 10 vegetation zones. Zone 1 is the coldest zone and supports plants like aspen. Zone 10 is the warmest zone. Gardeners here might plant ferns or palms. Is It Hot in Here? Deserts take up approximately one-third of the Earth's land surface!
Female mammals produce milk to feed their offspring. Sea level is determined by measurements taken over a year cycle. Also known as the "rooftop of the world.
There are five major vegetation regions: forest, grassland, tundra, desert, and ice sheet. The audio, illustrations, photos, and videos are credited beneath the media asset, except for promotional images, which generally link to another page that contains the media credit.

However, scientists disagree on how many biomes exist. Some count six forest, grassland, freshwater, marine, desert, and tundra , others eight separating two types of forests and adding tropical savannah , and still others are more specific and count as many as 11 biomes. Use these resources to teach middle school students about biomes around the world. Among Africa's many savanna regions, the Serengeti or Serengeti Plains is the most well-known.
The Serengeti is a vast, undulating plain that stretches 30, square kilometers 11, square miles from Kenya's Maasai-Mara game reserve to Tanzania's Serengeti National Park. The Serengeti is home to one of the continent's highest concentrations of large mammal species, including lions, hyenas, zebras, giraffes, and elephants.
Each year, more than one million wildebeest travel in a circular migration, following seasonal rains, across the Serengeti Plains. Their grazing and trampling of grass allows new grasses to grow, while their waste helps fertilize the soil. A terrestrial ecosystem is a land-based community of organisms and the interactions of biotic and abiotic components in a given area. Examples of terrestrial ecosystems include the tundra, taigas, temperate deciduous forests, tropical rainforests, grasslands, and deserts.
The type of terrestrial ecosystem found in a particular place is dependent on the temperature range, the average amount of precipitation received, the soil type, and amount of light it receives.
Use these resources to spark student curiosity in terrestrial ecosystems and discover how different abiotic and biotic factors determine the plants and animals found in a particular place. Trees are important because they provide valuable commodities, including wood, paper, and fruit.
