维管植物维管植物vascularplant具有木质部和韧皮部的植物。现存的维管植物大约有25~30万种,包括极少部分苔藓植物、蕨类植物、裸子植物和被子植物。维管系统(木质部和韧皮部)的发生是植物从水生到陆生长期适应环境的结果。维管系统的有效输导,使维管植物成为最繁茂的陆生植物。比较原始的维管植物的木质部中多只具管胞,故也可称这些植物为管胞植物。根据化石记录,原始的维管植物大约在距今3.6~3.7亿年以前的中泥盆纪,就已分成多条路线演化。有人认为现存的维管植物是由一条路线演化的。维管植物具有孢子体世代和配子体世代。孢子体非常发达,具有根、茎、叶等营养器官,并能产生具孢子的孢子囊。低等维管植物的配子体可以独立生活,但是形状细小,结构简单。到了种子植物,配子体更为退化,只有几个细胞在孢子内发育。维管植物的孢子体可以由有性生殖的合子或无性生殖的植物体的一部分或单个细胞形成。合子经过不断的细胞分裂,形成胚,从中分化出根端分生组织与茎端分生组织(见顶端分生组织)并建立起体轴系统。由胚发育成幼苗,并分化出各种组织系统。孢子体世代产生或多或少的孢子囊,每个孢子囊中可产生几个或多个孢子。产生孢子时,都经过细胞的减数分裂,染色体减半。由孢子中发育出配子体,从中形成颈卵器与精子器,或者形成更简化的样式。配子体中产生卵(雌配子)与精子(雄配子)。卵与精子结合成为合子,从而又开始新的孢子体世代。
