翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Absorption of water ： ウィキペディア英語版 Absorption of water Water is highly essential for plants for various metabolic activities. Land plants get their water supply from soil which serves as the source of water and minerals to them. The way in which water from soil enters roots, particularly to the root xylem, is called "mechanism of water absorption". Both Active and Passive absorption have been proposed for mechanism of water absorption. ==Active absorption== Without water any plant will die, so the absorption is vital. It is the absorption of water by roots with the help of metabolic energy generated by the root respiration.The force for water absorption originates from the cells of root due to root respiration.As the root cells actively take part in the process so it is called Active absorption. According to Renner, active absorption takes place in low transpiring and well-watered plants and 4% of total water absorption is carried out in this process. The active absorption is carried out by two theories which are, Active osmotic water absorption and Active non-osmotic water absorption. 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「Absorption of water」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.
