孢
1、某些植物和低等动物产生的有繁殖作用或休眠作用的细胞。离开母体后能形成新的个体。
2、通过孢子繁殖的一类植物,含菌、藻、苔、藓、蕨类等。
3、苔藓植物孢子体顶端产生孢子的膨大部分。成熟时开裂,散出孢子。
4、植物产生孢子的细胞或器官。有些植物有大、小孢子囊之分。大孢子囊产生个体较大而数量很少的大孢子,由它们发育成雌配子体;小孢子囊产生小而多的小孢子,由它们发育成雄配子体。
5、无性生殖的一种方式。母体产生孢子,孢子不经结合,直接形成新个体。如孢子植物和原生动物门孢子虫的生殖方式。
6、指植物世代交替中,产生孢子的植物体。孢子体一般具有二倍数的染色体。
7、植物生活史中具有二倍数染色体的植物体时期。如蕨类植物从合子形成到孢子母细胞的产生为孢子体世代。又称无性世代。
