摘　　要：本文讨论了胞间连丝、初生纹孔场和纹孔等细胞壁结构及其概念,分析了次生壁和细胞调亡之间的联系;提出了新名词“壁洞”和“功能纹孔”;澄清了各教材在木质素亲水性和传递细胞壁结构上的混乱。关于质体,本文指出了各教材通常过分强调叶绿体而忽视其他质体的现象。特别是,指出了一些教材误将秋叶变黄解释为叶绿体转化为有色体,而实际上这是叶绿体衰老所致。Herein,plant cell wall structures and their concepts,such as plasmodesmata,primary pit-fields and pits,are discussed,and the correlation between secondary walls and apoptosis of cells is analyzed.In addition,two new terms,“wall holes”and“functional pits”,are suggested,and some confusion about hydrophilicity of lignin and wall structure of transfer cells is clarified.With regard to plastids,it is pointed out that teaching materials usually overemphasized chloroplasts and neglect other plastids.Particularly,some textbooks misinterpret the yellowing of autumn leaves as the transformation of chloroplasts into chromoplasts,when in fact it is due to the consenescence of chloroplasts.
