How long can a tree live

In botany, trees are perennials with stems that grow elongated, supporting the branches and leaves of most species. In some uses, the definition of tree may be narrower, usually referring only to woody plants with secondary growth, plants that can be used as wood, or plants that grow to a certain height. In a broader definition, palms, ferns, bananas, and bamboos are also tree species. Trees are not a taxonomic group but include a variety of plant species that develop stems and branches as a way to rise above other plants in competition for sunlight. Trees tend to be long-lived, some trees can live up to several thousand years. Trees have been growing on Earth for at least 370 million years. It is estimated that there are about three trillion mature trees in the world. Trees usually have many secondary branches that are supported by the trunk from the ground. The trunk usually contains woody tissue for strength, and a network of vessels to carry nutrients from one part of the tree to another. In most trees, these vessels are surrounded by a layer of bark (bark) that serves as a barrier and protection. Underground, the roots branch and spread widely; Roots function to anchor the tree and absorb water, moisture and nutrients from the soil. Above the ground, the branches divide into smaller branches, twigs and shoots. The shoots usually produce leaves, which capture light energy and convert it into sugars through photosynthesis, providing food for the tree's growth and development. Trees usually reproduce by using seeds.

Tropical rainforests are one of the most biodiverse habitats in the world.

Flowers and fruit are also common, but some trees, such as conifers, have pollen cones and seed cones instead of flowers and fruit. Palms, bananas, and bamboo also produce seeds, but tree ferns produce spores. Trees play an important role in reducing erosion and maintaining the climate. Trees remove carbon dioxide from the atmosphere and store large amounts of carbon in their tissues. Trees and forests provide habitat for many species of animals and plants. Tropical rainforests are one of the most biodiverse habitats in the world. Trees provide shade and shelter for many species, wood for construction, fuel for cooking and heating, fruit for food and many other uses. In some parts of the world, forests are shrinking as trees are cut down to increase the amount of land available for agriculture. Because of its longevity and usefulness, the serung tree is considered sacred, and there are many forbidden forests or sacred forests in various cultures. Trees are also a common theme in various world mythologies. Although "tree" is a common linguistic term, there is no universally recognized definition of what a tree is, either botanically or in layman's language.

In the broadest sense, a tree is any plant with the general form of an elongated trunk, which supports branches and leaves for photosynthesis at some distance above the ground. Large shrubs such as papaya and banana are trees in this broad sense. In a narrower definition, a tree is a plant with a woody stem formed by secondary growth, meaning that the trunk thickens each year by growing outward, in addition to primary upward growth from the growing shoot. Based on this definition, herbaceous plants such as palms, bananas, and papayas are not considered trees regardless of their height, growth form, or trunk circumference. Tree species in the genus Dracaena, although monocotyledonous, have meristem-induced secondary growth in their trunks, but differ from the meristem thickening found in dicotyledonous trees. Apart from the structural definition, trees are usually defined by usage; for example, as a plant that produces wood. Tree growth habits are an evolutionary adaptation found in some groups of plants: by growing taller, trees are able to compete better for sunlight. Some trees are among the oldest living organisms now. Trees have a modified structure such as thicker trunks made up of specialized cells that add structural strength and durability, allowing them to grow taller than many other plants and spread their foliage over a wider area. This is mainly due to the fact that trees can decrease in size under harsher environmental conditions such as in mountainous and sub-polar regions.

Tree forms have evolved separately in other, genetically unrelated plant classes in response to similar environmental challenges. Evolution in trees is a classic example of parallel evolution. The largest tree populations are found in the tropics, and much of these areas have not been fully surveyed by botanists, making tree diversity and ranges less known.

The Quintessential Quintuplets (Japanese:, Hepburn: Go-Tōbun no Hanayome, lit. Japanese manga series written and illustrated by Negi Haruba. It was serialized in Kodansha's Weekly Shōnen Magazine from August 2017 to February 2020, with its chapters collected into fourteen tankōbon volumes. The series follows the daily life of a high school student Futaro Uesugi, who is hired as a private tutor for a group of identical quintuplets: Ichika, Nino, Miku, Yotsuba, and Itsuki Nakano. At the very beginning of the story, it is shown that the events are being told in a flashback, while an adult Futaro prepares to marry one of the Nakano Quintuplets whose identity is only revealed near the end of the series. under the Kodansha Comics imprint. The anime series is licensed in North America under a Crunchyroll-Funimation partnership. An anime television series adaptation produced by Tezuka Productions aired from January to March 2019 on TBS and other channels. The series is a commercial success, being the 5th best-selling manga in 2019, and the 3rd best-selling manga in the first half of 2020 in Japan. In 2019, the manga won the award for the shnen category at the 43rd annual Kodansha Manga Awards. High school student Futaro Uesugi is an academically gifted student that leads a difficult life-his mother has died, he has no friends, and on top of all that, his father has incurred a large amount of debt. An opportunity presents itself when the rich Nakano family transfers to his school.

The idea was denied by his editor-in-charge.

Futaro is promptly hired as a highly paid tutor. However, much to Futaro's dismay, he discovers that his five charges-identical quintuplet sisters of varied personalities-have no interest in studying at all and have abysmal grades. Some of the quintuplets are against having Futaro, whom they view as a stranger, in their apartment, but Futaro's diligent tenacity gradually convinces those girls to accept him and to improve their grades. Throughout the series, Futaro develops special relationships with each of the quintuplets. Through a flashforward, it is revealed that he eventually marries one of them, but her true identity is only revealed near the end of the series. The idea of ​​"a group of quintuplets falling in love with the same person" existed even before the serialization of Haruba's previous work, Karma of Purgatory (2014-2015), but was very simple at that time. The idea was denied by his editor-in-charge. A year after, after the end of Karma of Purgatory, he discussed with his editor-in-charge what to serialize next.

Uncommon Article Gives You The Facts on Manga That Only A Few People Know Exist

Among the few ideas being come up with, the "quintuplets" idea was included again, which was accepted by the editor this time. After failures in two to three serialization committees, finally, it was decided to have a one-shot manga published first. The one-shot received positive reviews and therefore went on to serialization. It was decided the protagonist should be quintuplets at the very beginning. When later the idea of ​​quadruplets and sextuplets was raised, it was rejected very quickly, around 30 seconds. Haruba said it might be a reference to Super Sentai when he came up with this idea. Similar to Super Sentai, Ichika (yellow), Nino (black), Miku (blue), Yotsuba (green), and Itsuki (red) are all represented by a color. The design of the quintuplets started from his favorite existing female characters from "some slice-of-life works only with girls", around 15 to 20 of them. The idea of ​​adding numbers in their names was after the design was almost confirmed.

The hair color of the Nakano quintuplets is different when being colored, which was suggested by Haruba himself, such that they are more distinguishable from each other. The hair color of the bride in the flashforward is, therefore, a colour-in-between. The flashforward showing that Futaro will eventually marry only one of the Nakano quintuplets was added in order to eliminate the possibility of Futaro marrying all five of them. It was also decided that all quintuplets would have negative feelings towards Futaro from the beginning, because Haruba wanted to write how their relationships improved from hate to love in the story, except Yotsuba, who acts as Futaro's guide for the development of the story. While it is often the norm for harem romantic comedy manga to have sexualized depictions of characters, Haruba has said that he tried to avoid this to some extent after Vol. In his opinion, showing panties which are being worn, ieTo keep the characters interesting, the sexy scenes were intended by him to be ambiguous but not straightforward, leading to readers' imagination. The swimsuit appearance of the Nakanos was finally revealed in Ep.
