Umbrella Thorn Acacia
The Umbrella Thorn Acacia grows in Africa. There are over 700 species of the Acacia in Africa. Umbrella Thorn Acacia is one of the most recognizable trees of the African savanna. It grows in sand dunes and rocky grounds of Africa's grasslands. Acacias grow in areas with annual rainfall as low as 4 cm. This tree can survive in 50°C temperatures during the day, and freezing temperatures at nights. The savanna that the Acacias live in is hot and dry in the respective summer of the Southern Hemisphare although at night the temperature can go below -18°C. During the winter months the savanna gets a lot of rain. The Umbrella Thorn grows up to 20 metres high and has a spreading, flat-tapped crown that gives it its name.

Saguaro Cactus
The Saguaro Cactus lives only in the Sonoran desert of southeasetrn California, southern Arizona, and northwestern Mexico. It has a smooth waxy skin and is covered two-inch spines. Because in desert there is very little water, the cactus has a storage place named ribs where the water is storaged when it rains. The cactus can grow in very limited areas below elevations of 3500 feet. It also has an amazing root system which is very shallow for such a big and heavy plant. It is similar to other cactuses.
Kaupo

Orchid
This plant grows in tropical rainforests. This plant lives on the bark of trees. This plant does not have access to the wet soil and needs ways to capture and store water for itself when it rains. Similar adaptations have for example bromeliads. They also grow in tropical rainforest and ´live on the bark of trees.

Bouganvillea
It grows in Amazon raingorest in South America. It has hooks to cling onto other plants and its leaves have drip tips to get rid of the rushing water. Without them it could break under the pressure of the water and it could not support it by itself. Carnivorous plants have similar adaptations, like Venus flytrap or pitcher plants.
Liis

Saguaro Cactus
The Saguaro Cactus lives in deserts, especially rocky terrain. It has downward pointing spines which make it easier to direct rainwater into the depressions of the cactus. The spines help to cool the outer skin. They also help redirect the wind and insulate the plant. If it did not have these adaptations it might face problems like dehydration. It could also get eaten by animals. Some other plants also have these adaptations. They live in Africa and are not cactuses. They are Euphorbias.

Barrel Cactus
The barrel cactus is found in the Mojave, Sonora and the Chihuahua deserts. The barrel cactus grovs in the desert washes and slopes, but can also be spotted growing along canyon walls.
Barrel cactus defends itself from animals with pulps which are very dangerous and sharp. Barrel cactus storages a lot of water to survive in desert. Cactus has not leaves it has pulps, because fom pilps water can not evaporate. Barrel cactus has light pulps to defend itself from Sun.
If this plant did not have these adaptations, the juice of the cactus should evaporate. If cactus did not have pulps, then animals could eat it.
There are only some other cactuses which have similar adaptations.
Siim

Bengal Bamboo
This plant grows in Southeast Asian forests. It is approximately 3 inches in diameter at maturity. This plant has straight green stalky culms. Leaves of this plant are long, narrow and green. It sucks up water from heavy rains that may cause flooding. It also provides shelter for many animals.
Rando

Cactus Mammillaria
Cactus Mammilaria grows mainly in deserts where the temperature remains above 8ºC. It has no leaves. It has spines. Those spines help to defend the cactus. Many animals want to destroy it because of its water inside. Without the spines the the water might evaporate. If cactus did not have these adaptations, some animals might kill the plant. Other cactuses which live in the same area with Mammalia have similar adaptations.

Durian
Durian grows in lowland rainforests, and is native to Borneo, Indonesia and Malaisia. It is thought to be one of Southeast Asia's most ancient and primitive trees.
Durian's bark is dark beown, rough with many vertical splits. It peels off irregulary, ana adaption to prevent epiphytes, lianas and parasitic vines from growing on it.
Flowers have strong odor. It attracts its principle pollinator, a small bat called a Dawn Bat.
The Durian fruit has a very strong odor. This is an advertisement for all the animals that eat it. Durian's fruit's odor reminds decayed onons, but people eat it and it is very popular.
The Durian is dependent on a small nocturnal bat (the Dawn Bat). Without the bat the Durian can not fruit. The importance of the Dawn Bat was actually discovered a few years ago. Without the bats there would be no Durian, which to many people in Southeast Asia is unthinkable.

Umbrella Thorn Acacia
Umbrella Thorn Acacia grows in the African savanna. It grows in sand dunes and rocky grounds of Africa's grasslands.
Umbrella Thorn Acacia has many adaptions to survive in the savanna. First, it has a deep taproot so that it could get water during the dry season. Then Acacia's small leaves prevent water loss. And Acacia's umbrella-shaped tops enables the leaves to catch as much sunlight as possible.
If the Acacia did not have these adaptations it would not survive the dry season. It would not get water from the ground if its taproot were not so deep and if the leaves were bigger then the water loss during dry season would also be greater. Some other plants have similar adaptations. For example the Manketti tree also has deep taproots to survive the dry season.
Liilia

Baobab
The Baobab is found in the savannas of Africa and India, mostly around the equator. In wet months baobab stores water in its thick and corky trunk. If Baobab did not keep water inside its trunk, then Baobab would dry because there are nine dry months ahead in savanna. Fire is very usual in savannas and for that reason Baobab has fire-resistant trunk.
Similar adaptions has Manketti tree, which has a trunk that can store water and thick bark to resist annual fires.

Barrel cactus
Barrel Cactus grows in American deserts. Largest Barrel Cactus grows in North America.
This cactus storages water in its fleshy tissues. Under the skin is allocated the storage of water and food for the plant. Catuses have barbs in place of leaves, thats why they have more water in them. This is a type spongy tissue and can take up to 85% of the plants volume. This is a major adaption in the desert. Because the plant remains completely alive during the dry season and there is no need for it to dry up and lose everything, makes it possiblefor the plant to grow large sizes.
If cactus did not have water in its fleshy tissues, then it would dry up, because there are dry seasons in desert. If cactus had leaves then it would lose more water. Some other cactuses (Crimson Hedgehog cactus, Poncohe Prichley Pear Cactus, Saguaro Cactus and Opuntic Cactus) have similar adaptions in this environment.

Desert Ironwood
The Desert Ironwood is a slow-growing, bluish gray-green tree with a broad crown, which is 15-25 feet tall, but can grow to 30 feet. Gray-green leaves, with two spines at each base, firmly divided into many leaflets. Old leaves fall after bloom with new ones replacing them quickly. Plant grows near washes where water is usually available. Wood is hard, heavy and dense, and valued for carving. Spiny branches are slow to develop. Ironwood trees provide among other things roosting sites for hawks and owls. This tree blooma in May and June.

Cactus Mammillaria
Cactus Mammillaria grows mainlyin deserts. It has no leaves It has spines. Those spines help to defend the cactus. Many animals want to destroy it because of its water inside. Without the spines, the water might evaoprate. If cactuses did not have these adaptions some animals may kill the plant. Also all other cactuses which live in the same area as Mammillaria have similar adaptations.

Umbrella Thorn Acacia
Ambrella thorn Acacias grow in African savannas. One of the Umbrella Thorn's adaptions to hot and dry conditions is a deep taproot which can reach 115 feet under the ground. The little leaves of the Umbrella Thorn prevent water loss. The acacia's umbrella-shaped tops enable the tree to capture large amounts of sunlight with the smallest possible leaves. The thorns are used to keep the savanna animals away from eating the leaves, flowers and seedpods. If it did not have taproots, then it would not get the water during the dry spells. If it had little leaves then it would lose the water more quickly than with small leaves. When it did not have thorns then the animals would it it.
Jackalberry tree has similar adaptions. It has also small leaves, so it does not lose so much water.
Merili

Bristelcone Pine
Those trees are the oldest in the world. They are as old as pyramids are. They live in arid, scattered mountain areas. The oldest Bristelcone trees usually grow in at elevations of 10 000 feet to 11 000 feet. The oldest tree is "Methuselan", which is 4789 years old.
It is a multi-trunked tree twisted by the elements. Because the needles can live twenty to thirty years, the tree does not need to expend much energy on adding new needles.
Marten

Desert Lily
Desert Lily grows in Mojave and Sonoran deserts of Southeastern California, western Arizona and Northwestern Mexico. It can be found in sandy desert flats and slopes below 2500 feet.
Native Americans used the Desert Lily bulb as a food source. These bulbs can remain in the ground for several years, waiting for enough moisture to emerge.
Plant grows only little time, but when bulb goes under ground then that plant lives longer time.
Karolina

Ocotillo
Ocotillo grows in America's and Northern Mexico's deserts. Ocotillo is a desert success story, it is adapted to its environment by sheding small leaves during dry spells. It can also grow new leaves with 5 days. It has a shallow but wide root system, which it uses to gather rain-water.
Roland

Bougainvillea
They are thorny, woody vines growing anywhere from 1-12 meters tall, scrambling over other plants with their hooked thorns. The thorns are tipped with a black waxy substance that is easily left in the flesh of an unsuspecting victim. The leaves are 4-13cm long and 2-6cm broad. Bougainvilleas are popilar ornamental plants in most areas with warm climates.

Chuparosa
Chuparosa is a species shrub native to the deserts of South California, Arizona and Northern Mexico. Rocky slopes and along desert washes, mostly below 25 000 feet. This is a low bush which grows in dry hot regions in the sand or rocky terrain of the desert floor.
Rahel

Organ Pipe Cactus
Organ Pipe Cactus grows in small areas of the Sonoran desert but only from Southwestern Arizona to Weatern Mexico. The plant is south facing. The Organ Pipe Cactus grows in hot sunny slopes. Because of the high temperature and lack of water the plant has waterstoring trunks what are about 6 inches in diameter.
Katlin

Jambu (Watery Rose Apple)
This plant grows in the rainforests, especially in places where rain can fall right on it. This plant has little places in its trunk, where it can collect water. The crown is open and non-symetrical for helping to collect water because it needs a lot of it to survive.
Andres

Coconut tree
Coconut tree grows in hot areas. Its leaves are long and bright green. It has stout trunks. Coconut tree is about 20-30m long and it has smooth bark. Coconut tree is the most important fruit in the tropics for it gives precious water full of potassium and other minerals.

Datura
All species of Datura are poisonous. Datura emits halucionogenic alkaloids so it keeps animals away from itself quite successfully.
Alar
