含义:硅藻
     硅藻是一类具有色素体的单细胞植物,常由几个或很多细胞个体连结成各式各样的群体。硅藻的形态多种多样。 硅藻常用一分为二的繁殖方法产生。分裂之后,在原来的壳里,各产生一个新的下壳。盒面和盒底分别名为上、下壳面。壳面弯伸部分名壳套。上下壳套向中间伸展部分,称相连带。
    硅藻属于不等长鞭毛类这一大类群,这一大类群既有自养生物(如金藻、巨藻)又有异养生物(如水霉)。黄棕色叶绿体是不等长鞭毛类的一个特征,这种叶绿体有四层膜,含有类胡萝卜素、墨角藻黄素。硅藻个体通常无鞭毛,但其雄配子具不等长鞭毛,同时与其他类群相比其鞭毛缺乏茸毛。
    硅藻在食物链中属于生产者。硅藻的一个主要特点是硅藻细胞外覆硅质(主要是二氧化硅)的细胞壁。硅质细胞壁纹理和形态各异,但多呈对称排列。这种排列方式可作为分类命名的依据。但是这种对称并不是完全的对称,因为硅藻细胞壁的一侧比另一侧略大一点,这样才能嵌合在一起。化石遗迹显示,硅藻最迟起源于早侏罗纪时期。仅中心硅藻类的雄配子具鞭毛,可以游动。硅藻一直以来是一种重要的环境监测指示物种,常被用于水质研究。分类上归为一纲,辖下有中心硅藻目及羽纹硅藻目。此外也是近海的优势类群。
