Achenes are monocarpellate (formed from one carpel) and indehiscent (they do not open at maturity). Achenes contain a single seed that nearly fills the pericarp, but does not adhere to it. In many species, what is referred to as the "seed" is actually an achene, a fruit containing the seed. The seed-like appearance is owed to the hardening of the wall of the seed-vessel, which encloses the solitary seed so closely as to seem like an outer coat.〔 ==Examples== The fruits of buttercup, buckwheat, and cannabis are typical achenes. The achenes of the strawberry are sometimes mistaken for seeds. The strawberry is an aggregate fruit with an aggregate of achenes, and what is eaten is accessory tissue. A rose also produces achenes. Each fruit, called a rose hip, holds a few achenes. 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「Achene」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.
