#10 Kauri tree

#10 Kauri tree

The Kauri tree, also known as Agathis australis, is the oldest tree in the world, the age of this tree is about 1,200 years old. The Kauri tree grows by developing column like trunks with spreading crowns to be balanced while growing. For the Kauri tree to grow, they need to take 1,700 years to be fully grown. The Kauri tree can fully grow to 60 m! The only Kauri tree located is in The Waipoua Forest in New Zealand.

#9 Quiver tree

#9 Quiver tree

The Quiver tree, also known as Aloidendron dichotomum, have a unique adaptation. The trunk and the branches of this tree hollowed out to store water from the soil. Because the tree is hollowed, people uses the branches to make arrows and they use the trunk to keep water, meat and vegetables cold. The San People in South Africa and Namibia created the name of this tree. This tree can be located in deserted and semi- deserted areas. This plant have Anthraquinones to attract insects or other pollinated animals, their leaves are aloe like leaves prevent water vapor loss in the plant, their branches have a powder to protect the plant form the UV light, their root are separated from each other to consume small amount of water in the soil, they pollinate by winds and desert whirlwinds. Because their trunk is hollowed, their adhesion and cohesion are very thin for the small amount of water from the roots.

#8 The Rafflesia flower

#8 The Rafflesia flower

The Stinking Corpse lily, also known as Rafflesia and Titan Arum, is the largest flower in the world. It can grow up to three feet in diameter and weigh over 20 pounds. It got its name by the odor of the flower, it produces strong odor of decaying flesh. It can be located in the wild tropical regions in Asia. This plant is describe as an angiosperm, because of its scent the flower attracts flies and beetles. This flower doesn't have leaves. The flower uses cross pollination from a pollinator by hovering on the flower. After pollination is successful, this flower creates four millions seeds inside the flower and they use wind pollination. The filaments of this seeds grows only through germination consuming water.

#7 Baobab trees

#7 Baobab trees

The Baobab trees can be describe as the tree of life because it provides food, water, shelter, and medicine. It can also be describe as "the upside down tree" because the branches of the tree looks like roots from the tree. To know the life spam of this tree is by radiocarbon dating because the trunk of the tree doesn't have growth rings and it shows that the life spam of this tree can be up to 2,000 years old. This trees are located in Madagascar, Africa and Australia. They create flowers that have white flexible petals with a lot of long filaments and stamens at the end of the filaments, they pollinate at night by a bat pollinator. This flowers create a wood, oval like fruit that contains seeds surrounding the pulp.
Fun Fact: If a person takes a flower from the Baobab tree, the person will be devoured by lions.

#6 Hydnora Africana

#6 Hydnora Africana

The Hydnora Africana (Hydnora Euphorbia) is a parasitic flower that have an unusual appearance of a fungi but it open up as a flower. This flower doesn't have petals, but this flower attract pollinators by their scent and the pollinators gets inside the flower and trapping the pollinator in the flower's tube to the anther to collecting pollen. The stigma of the flower is located down the center of the plant. The roots of the plant gets attached to other plants to collect water from them and for adhesion and cohesion of the plant. Their fruit is produce on the ground, it has the similar taste and texture as a potato and they produce 20,000 seeds per fruit. Animals spread the fruit's seeds, leaving the seeds on the ground for germination and the seeds germinate by consuming water from the rain, leaving seeds to produce roots to other plants to survive. Located in South A

#6 Suicide palm

#6 Suicide palm

The Suicide palm trees (Tahina spectabilis) gets it's name by its demise, the tips of the stems creates tiny flowers by an explosion to pollinate and create fruits, the pollinators collect nectar from the flowers. The plant's color attract the pollinators by their color but their color exhaust the plant by draining their nutrients and eventually dies. Their flower blossom once every 100 years before the trees dies. Their flower compares to a Chinese cousin, can be pollinated by air or by pollinators. The flower of the palm trees are located in the trunk of the trees. Hermaphroditic flowers: Each flower has both male and female flowers parts on the same flower and there are 3 different types of flowers that the palm trees creates, Monoecious species, Dioecious, and Hermaphroditic flowers. These type of flowers can cross-pollinate or self-pollinate. It's roots are created by the regions of the trunk and the process is called the root initiation zone and if the root gets cut, it creates a new root behind the cut root. Located in Madagascar.

#5 Sensitive plant

#5 Sensitive plant

The Shame plant (Mimosa pudica) is a plant that become shy if touched, the leaf folds to defend themselves. While the leaf is folding, the stems of the plant force the water out from the cells and makes the leafs collapses. Each spikes of this plant is their filaments with white filaments. Their stem are up to 2.5 mm long , depending of their thorns. During the summer this plants create produce 700 bristled seeds and spread by fur, feathers or people clothing. Their fruits are from 2-8 pods that measure 1-2 cm. Their stem are covered with prickles with reddish brown or purple. This plants can be discovered in South and Central America.

#4 The dragon's blood tree

#4 The dragon's blood tree

The dragon's blood tree or the Socotra dragon tree (Dracaena cinnabari) is a relative to the palm tree in Socotra, Archipelago in Yemen. This tree as an aspect of an umbrella but researchers found out that this tree one of the umbrella species that exist around their world and their purpose is to "protect" animals and their habitat. This tree doesn't have a xylem or phloem but they use their stem and roots as a secondary thickening, a formation of new tissues by repeating cell division in the cambium of the tree These tree produces small flowers that are white or green colored flowers, these flowers are produced at the end of the branch of the tree. Their seeds are measured by 3-4 mm in diameter, and they can spread out by birds or other animals. Some seeds also tend to grow near a tree to provide shade and prevent evaporation on the seeds and consuming the same amount of water from the tree next to the seed. Their fruits is a orange-red berry like fruit that contains 1-3 seeds, the fruits matures by 5 months.
Fun Fact: They got's its name by resin, if someone cut the trunk, branch and/or leaf the resin comes out bright red.

#3 Sea Urchin

#3 Sea Urchin

The Sea Urchin, (Euphorbia obesa) also known as Baseball plant is a ball shaped cacti that the stem of this plant becomes a ball over time. The color of the stem are grey-green marked with red-brown or purple marks. While the stem is developing, the leaves of the plant falls off because the leaves accumulate more space then the developed sea urchin. The transverse of the plant have a small amount of pholem on top and a large amount of xylem. The flowers can be located on top of the urchin, they can create female flowers but sometimes the urchins create male flowers. Male flower's Cynthia have pollen and female flower's appear only on female urchin. Their structure are very different to each other, the size and the appearance of the flower. The male flower structure have a long pedicel and a very small stamen and the female flower structure have a very small pedicel but with 3 styles at the end of the flower. Their pollination consist on either cross-pollination or self-pollination, if pollination succeeds the female flower becomes bigger into a capsule of 7 mm and inside the capsule its creating seeds. The fruits that the urchin creates a 3 angled capsule containing 3 grey colored seeds inside. Each year, this type of plant produce 150 seeds.
Fun Fact: This plant can leave a white milky substance that can be poisonous

#2 Hot lips

#2 Hot lips

The Hot lips (Palicourea elata) got its name by their appearance of someone's lips. The plant forms lips because the bracts of the plant is developing a flower. They get their water by collecting some of the water in the trees. Their leaves are actually their bracts because this plant evolved their leaves to attract more pollinators. The stigma of the plant is located inside the plant before pollination. These plants creates 3 flowers and the flowers are produced in a small tree from the rain forest, their flowers are star like white to cream color flowers and its shape attract pollinators like hummingbirds and butterflies to cross pollinate from other plants. The flower's anther and filament is located next to the plant's petal If pollination is successful, the bracts will open to create flowers to collect of receive more pollen if necessary and create a small bluish-black berries.

#1 Rat-eating pitcher plant

#1 Rat-eating pitcher plant

The Rat-eating pitcher plant (Nepenthes attenboroughii) is a 4 foot pitcher shaped carnivorous plant that uses its essence and nectar to attract animals to consume them. Their leaves make this shape to contain acid-like juices to dissolve their victims and closing the plant's trap. Their flower can be located on top of the pitcher plant to protect pollinators from the scent of the pitcher plant. The flower have a curve st the end of the stem to attract pollinators that is near the pitcher. The flower's stigma and be different from the other pitcher while blooming, but sometimes the stigma have a shape of an upside down umbrella to hold the pollen for the pollinators. The filaments and the anther of the flower are short for the stigma to hold the pollen. If pollinators are unsuccessful, these plants can self-pollinate because the stigma and the pollen are very close to each other. The stomata of the leaves collects water from the rain, the leaves protects the acid inside the plant to not damage the plant's digestive system. This plant can be located in the rain forest in the Philippines.
Fun fact: This plant can digest insects and animals that are smaller than the plant, they got the name the rat-eating pitcher plant because it can eat rats that are almost its size and after this plant digest mice, they spit out the mice out and looks like the rat has been sucked out from the inside.
