- 中文摘要:
植物細胞之異於動物細胞最主要在於其具有一層質地稍硬的外殼,稱為細胞壁。當植物細胞尚未成長定型之前,僅具有初生細胞壁,這是一種具有生命力的物質,可隨著細胞的生長而生長,並控制著細胞的生長速率、生長方向以及細胞的形狀等等。本文採用 Albersheim 等人所提供之初生細胞壁模式圖,將其組成份、結構型式以及生長、延展等性質作一詳細的說明,並概略敘述次生細胞壁與中膠層的組成和性質。有關細胞壁生長方式的假說,亦在文中討論之。
- 英文摘要:
Whether the possession of the cell wallmakes the most significant difference betweenplant cells and animal cells. In growing planttissue, the cells possess only primary cell wallwhich is capable of change in size and shape asthe tissue differentiate. In the current article, wedescribed the model of the primary cell wallproposed by Albersheim et al. to elucidate thecomponent, structure, growth and extension ofthe primary cell wall. In addition, the rigidsecondary cell wall and the less rigid structureof middle lamella were also described. Wealso discuss the models on cell wall growth asproposed by several authors.
