其主要特征是:藻体为单细胞或连成各式群体;细胞壁由硅质和果胶质组成,而且在结构上都是由上壳和下壳套合而成,纵断面观呈"肥皂盒"形;在上下壳的壳面上有花纹,花纹排列的方式主要分为两侧对称和辐射对称两大类,为分类上的最重要依据;能运动的种类在壳面都有壳缝,不能动的种类均无壳缝;色素体片状或带状,1个或2个,或为多个小盘状,黄绿色或黄褐色,含叶绿素a、c,还含有墨角藻黄素和硅甲黄素等光合色素;贮藏物质主要为油滴;繁殖方式主要为细胞分裂,硅藻的细胞分裂的明显特点是:每次细胞分裂所产生的2个子细胞中,仅有1个和母细胞等大,另1个则稍小。

This suggests persistent expression of SiDIV and ceasing of SiCYC1A and SiCYC1B in late peloric flower stage may generate the actinomorphic flower.
综此推测,变异型的花发育成辐射对称可能是由於开花晚期时SiCYC表现量下降及SiDIV持续表现,造成花发育后期两侧对称性的无法继续维持,而成了辐射对称花形式。
