兰藻即藻门(Cyanophyta)或称粘藻门(Myxophyta),亦有人称兰藻纲(Cya-nophyceae)或粘藻纲(Myxophyceae)。目前,通称兰藻类或兰绿藻类。 兰藻类分布极其广泛,适应力强,从热带到极地,从高山到海洋;无论是淡水、咸水或是温泉中都能生存。而且从古至今皆有。这样,可根据兰藻类的演化特征将今论古,古今对此,反复地进行探讨。 兰藻类是具有叶绿素的单细胞或多细胞 Cyanophyta, or Myxophyta, also known as Cya-nophyceae or Myxophyceae. At present, commonly known as blue algae or blue-green algae. Blue algae are extremely broadly distributed and highly adaptable, from the tropics to the polar regions, from mountains to the oceans; whether fresh water, salt water or hot springs. And since ancient times are all. In this way, according to the evolutionary characteristics of blue algae this ancient, ancient and modern to this repeatedly discussed. Blue algae are chlorophyll-containing single or multicellular cells
