精子器

Antheridial cell The cell from which the antheridium develops.

精子器细胞：从精子器发育而来的细胞。

It is motile and is produced in an antheridium, except in certain gymnosperms (e.g.Cycas, Ginkgo) in which antherozoids develop from the generative cells of the pollen tube.

除了在一些由花粉管的生殖细胞产生配子的裸子植物中（铁树 Cycas，银杏 Ginkgo ），通常是由精子器产生的并且会游动。

Antheridium The male sex organ of the algae, mosses, liverworts, hornworts, ferns, horsetails, clubmosses, and fungi.

精子器：藻类、苔藓、地钱、蕨类等植物中的雄性生殖器官。

Basal bodies are the structures developed from bicentriole, the branched blepharoplast and blepharoplast, respectively, depending on the specific group of ferns concerned.

鞭毛、基体和多层结构中的微管带形成了游动精子三个独特的微管列阵，由于微管蛋白的后修饰作用这些微管列阵十分稳定；centrin是运动器中的重要成分，但功能尚不清楚，可能和细胞骨架及运动器的构建有关。

There formed segregating cavities between spermatocyte cell-wall and spermogonium cell-wall and osmiophillic layers outside spermatocyte cytoplasmalemma, which indicated that the spermatocytes had begun to gradually break away from the male gametophytes and embark on independent development.

精母细胞与精子器的璧细胞之间形成了分离腔，在精母细胞质膜外形成了嗜锇层，这些结构的形成说明精母细胞已经开始与雄配子体逐渐分离，进入独立发育的阶段。

The sex organs appear about 5 weeks after sowing. The antheridia consist of 3 cells. The archegonial neck usually consists of 4 rows and 4 columns of cells at maturity.

播种5周左右开始有性器官出现，精子器由3细胞组成，成熟颈卵器颈部由4列细胞组成， 4层细胞高。

A kit for vaginal self-use by a female patient in protection against contracting viral infection and against conceptions as a result of normal heterosexual intercourse, said kit comprising a vaginal applicator comprising a vaginally insertable tubular member having a length of about five inches, and having an aperturable distal end adapted to be positioned adjacent to the patient's cervix when the applicator is fully inserted into the patient6's vagina, and at least one unit dose of the spermicidally and virucidally effective formulation of claim 1, said unit dose being form about 5-10 mls thereof.

一套女性患者阴道自用的工具，以防止感染病毒或因异性间正常性行为而受孕。该套工具包含一个阴道给药器（由一个长约5英寸、末端有孔眼、可插入阴道的管状构件构成，当给药器完全插入患者阴道后，构件的末端适合置于患者的宫颈附近），以及至少1个单位剂量（5-10毫升）的、能有效杀死精子和病菌的权利要求1中的配方。

A sheathlike outgrowth of tissue in bryophytes protecting the archegonia or antheridia in certain liverworts.

总苞：1 是一种由被子植物花序下方的环状苞叶组成的保护结构。2 是苔藓植物外方具有的鞘状结构，在某些苔类中用来保护颈卵器或精子器。

In organisms showing sexuality, the gametes are of two types: male and female. They may be produced in special organs (e.g. carpel and anther in angiosperms, archegonia and antheridia in lower plants and some algae). The gametes may be derived from the same parent AUTOGAMY0 or from two different parents

在显示性别差异的器官中，配子体分两种：雄配子与雌配子，二者可能在特殊器官中产生（例如：被子植物的心皮或其它结构、低等植物及某些藻类的颈卵器和精子器）配子可以来自同一亲本或由两个不同亲本分别产生。

Moreover, the extremely slow development of gametophyte and time interval between the appearance of antheridia and archegonia resulting from the inherent physiochemical property of red soil make it impossible to fertilize and generate sporophyte.

此外，红壤固有的理化性质导致扇蕨配子体发育极其缓慢、精子器和颈卵器发生的时间间隔过长使其不能受精产生于包子体。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
