Heat is generated in the mitochondria, as a secondary process of cellular respiration called thermogenesis. Alternative oxidase and uncoupling proteins similar to those found in mammals enable the process, which is still poorly understood. ==The role of thermogenesis== Most scientists are not completely sure why thermogenic plants generate large amounts of excess heat, but most will agree that it has something to do with increasing pollination rates. The most accepted theory, states that the produced heat helps in spreading chemicals that attract pollinators to the plant.〔(【引用サイトリンク】url=http://www.howplantswork.com/2010/01/16/plants-that-warm-themselves/ )〕 For example, the Voodoo lily uses heat to help spread its smell of rotting meat.〔(【引用サイトリンク】title=Plant of the month: Voodoo Lily )〕 This smell draws in flies which begin to search for the source of the smell. As they search the entire plant for the dead carcass, they unknowingly pollinate the plant. In this particular case, heat helped spread a scent, which in turn helped pollinate the plant.〔(【引用サイトリンク】url=http://www.newscientist.com/article/dn16316-giant-stinking-flower-reveals-a-hot-secret.html )〕 Other theories state that the heat may provide a heat reward for the pollinator. By giving off heat, pollinators will be drawn to the flower to warm up. While the insect is getting heat, it will also be pollinating the plant by spreading pollen that is stuck to its body. This theory is less supported, because most thermogenic plants are found in tropical climates. Yet another theory states that the heat helps protect against frost damage. This would allow the plant to germinate and sprout earlier than normal plants. For example, the skunk cabbage generates heat, which allows it to melt its way through a layer of snow in early spring.〔(【引用サイトリンク】title=Skunk Cabbage )〕 The heat, however, is mostly used to help spread its pungent odor and attract pollinators. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Thermogenic plants」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
