exospore:外生孢子
(3)内生孢子(endospore)和外生孢子(exospore):只在管藻目和其他目的少数属中发生,不很普遍. 在母细胞内由原生质分裂成许多小型、圆球形的内生孢子,母细胞破裂后,孢子释放、萌发成新的藻体. 一些种类孢子在顶端细胞内形成并释放,
-
Mucor Mucedo:大毛 霉
融成一个细胞,称为配子囊. 相接触的两个配子囊之间的横隔消失,细胞质和细胞核互相配合,同时外部形成厚壁,即为接合孢子. 接合孢子主要分布在接合菌类中,如高大毛霉(Mucor mucedo)和黑根霉(Rhizopus stolonifer)产生的有性孢子为接合孢子.
-
pollen tube:花粉管
它和用孢子繁殖的蕨类植物最大的不同有三点:第一,产生花粉粒(pollen grains)和花粉管(pollen tube). 花粉母细胞或称小孢子母细胞经减数分裂产生单核的花粉粒,不脱离母体萌发成若干细胞的花粉粒,此时由风或其它昆虫等传粉,
