In lower plants such as mosses and liverworts the persistent vegetative plant is haploid , the sporophyte being a relatively short-lived phase .
在苔藓,地钱这样的低级植物中,习见的植物体是单倍体,孢子体存在时间较短。
Haplobiontic describing life cycles in which only one type of somatic body is formed , which may be either haploid or diploid , i.e. either the sporophyte or the gametophyte generation is missing .
单型世代:生活史中仅有一种生活的单倍体或二倍体的植物体,也就是说其孢子体或配子体世代缺失了。
In bryophytes ( mosses , liverworts and horworts ) the haploid gametophyte is the dominant phase of the life cycle and the sporophyte is represented only by the capsule , seta , and foot .
在苔藓类植物中(苔藓,地钱,金鱼藻)单倍的配子体占生活史的主要部分,孢子体包括孢蒴、蒴柄和基足。
The growth of cladophora , when observed under the microscope , starts with precursors and extracellular polymeric substances ( eps ) secreted by the bacteria on the substrate in which the sporophyte and gametophyte attach and then begin to grow .
