囊孢子的

Therefore,the author concluded that the cryptosporidia on the surfaceof respiratory tract,cloaca and BF belonged to Cryptosporidium baileyi.

据此，作者认为：寄生于鸡、鸭、鹅呼吸道、泄殖腔及法氏囊的隐孢子虫均属于贝氏隐孢子虫。

The other cells of the tetrad undergo degeneration. The mature embryo sac consists of an egg apparatus, a central cell, and 3 antipodal cells. The embryo sac is a monosporic Polygonum type. The zygote develops into a mature embryo going through proembryo, globular, heart, and torpedo stages.

胚囊发育类型为单孢子蓼型胚囊； 2胚的发育经过原胚、球形胚、心形胚和鱼雷胚等阶段发育为成熟胚；胚柄在球形胚时期最发达，但胚柄短小，只由3个扁平细胞组成，之后逐渐退化。

In the gymnosperms the megaspore gives rise to a cell that is termed the embryo sac because of its similarity to the angiosperm structure.

在裸子植物中，大孢子也产生一个细胞，因为它类似于被子植物的胚囊细胞，故也可以称之为胚囊。

In the late of April of the second year, male inflorescences unbound and pollinated. When female inflorescences accepted the pollen grains, ovary development was increased in early May. With the development of either of the two ovule, funiculus, integument and nucellus were differentiated. Embryo sac mother cell came into being and the meiosis begins. Then fuctional megaspore developed into matured embryo sac that contain eight nucleuses. In the end of May, double fertilization generated.

次年，4月下旬，雄花序解螺旋散粉，雌花序开花授粉；5月上旬，雌花序授粉后，迅速增长，子房膨大，两个胚珠分化出珠柄、珠被和珠心，珠心中产生孢原细胞；5月中下旬，大孢子母细胞形成并减数分裂，功能性大孢子形成成熟的八核胚囊；5月底，发生双受精。

The results are summarized as follows: tin the polygonum embryo sac of tetraploid grape , megaspore telrad arranged in straight line.

结果如下：在四倍体葡萄的蓼型胚囊中，四分体孢子呈直线排列，合点端的大孢子发育胚囊。

The sori become enclosed by the growing together of fertile fronds, and the spores are not liberated until the sporocarp decays and ruptures.

随着植物体繁殖器官的同步生长，芽孢囊群逐渐被封闭。直至孢子果腐烂破裂时孢子才能散出。

Could be observed on 10th day after pollination, archesporial cell on 20thday, megasporocyte on 24th day, the functional megaspore on 30th day; and 8-nucleate embryo sac on 41th day. And then double fertilization finish and early globular embryo emerg.

授粉10 d出现指状突起，20 d形成胚珠原基，24 d大孢子母细胞发生，30 d功能大孢子形成，41 d发育为成熟的八核胚囊，而后完成双受精发育成早期球形胚。

Filicinophyta The largest phylum of spore-bearing vascular plants comprising the ferns and including about 12000 species. It is divided into two main groups, the LEPTOSPORANGIATE ferns and the EUSPORANGIATE ferns.

真蕨门：是有孢子维管植物中最大的一个门，包含真蕨类，约12，000余种，主要分为薄囊蕨和厚囊蕨两种。

Scanning electron microscopy showed that the spores were shrinking and collapsing, and the mycelium walls were ramified and nodulated under combined application of Na2SeO3 65.714mg/kg+LaCl3 53.002mg/kg. Furthermore the surface ornamentation of cystidia became fuzzy and disappearing, and some cystidia were disappearing and collapsing.

扫描电镜观察结果表明，与对照相比，中浓度硒镧配施（Na2SeO3 65.714mg/kg + LaCl3 53.002mg/kg）时，孢子由正常椭圆形变成全部萎缩，菌丝粗壮；囊状体在较低硒镧配施浓度（Na2SeO3 43.810mg/kg + LaCl3 35.335mg/kg）处理时表面纹饰模糊、消失，个别囊状体破裂，表面带有藤蔓状的组织。

This causes the stomium to rupture, exposing the spores within the capsule.

孢子囊中的孢子在囊壁破裂时会散出。

The objective is to subjugate and discourage the people, because that allows the elite to continue to rule unopposed.

其目的是压制和打击人民的积极性，因为这可以让实权派继续统治不会沦为反对派。

GOD,this is the second time you vanquished me!

天啊，这是第二次你打败了我！
