Alternation of generations can be divided into two basic types, one for the same shape alternation of generations, the sporophyte and the gametophyte in the morphology similar size, only cytology and physiology are different, such as Ulva, etc.; another type of shape alternation of generations, that is, in the sporophyte and gametophyte morphology and size are also significant differences.
世代交替又可分为两种基本类型,一为同形世代交替,即孢子体和配子体在形态大小上类似,仅在细胞学上和生理上有所不同,如石莼等;另一类型为异形世代交替,即孢子体和配子体在形态结构和大小上也有明显差异。
