精子器

One of two sperm get into an archegonium and fused with egg. The nucleus of fertilized egg began to divide, and the walls were formed after the third division. The eggs without fertilization divided two times and then disappeared.

雄配子体产生的两个精子中的一个进入颈卵器与卵细胞结合形成受精卵，受精卵核到第3次分裂形成细胞壁，没有受精的卵细胞还要进行两次有丝分裂后才消失。

In the present review, we focus on some of the recent advances and some key developmental events revealed in the fertilization process, including the role of the egg apparatus in guiding pollen tube orientation, sperm cell movement to their targeting cells, interaction between gametes, egg cell activation, and onset of embryogenesis and endosperm development.

本文着重讨论受精作用的若干重要发育事件，包括受精前卵器细胞对花粉管向胚珠定向生长的近距离引导信号，精子的靶向运动，精、卵细胞相互作用和配子融合后卵细胞的激活与中央细胞发育的启动等。

5 ml fresh chicken semen was divided into five groups equally, each of which was diluted at the volume ratio 1:4. With the group without magnetic treatment as the control, the other four groups were magnetized for 6, 12, 24 and 48 min in the self-made magnetizer, respectively. Subsequently, all the five groups were stored at 2-4 ℃, and the sperm motility, survival time, survival index and deformity rate were observed regularly.

方法］将5 ml新鲜精液平均分为5份，每份按1：4进行稀释，其中1份为对照组，不作磁化处理，其余4份分别放入自制磁化器中磁化6、12、24、48 min，5组均置于24℃的冰箱中保存，定时观测精子活率、存活时间、生存指数和畸形率。

The locomotory apparatus that emerges during the spermiogenesis consists of the multilayered structure, basal bodies, flagella and accessory structures.

精子发生过程中形成的运动器的各部分结构包括鞭毛、基体、多层结构及附属结构；基体是细胞中新形成的结构，在不同类群的蕨类植物中分别由双中心粒、分支生毛体和生毛体产生。

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。
