囊孢子

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。

Cryptosporidium oocysts were separated from the faeces in a cattle farm and identified as Cryptosporidium muris according to their morphology, structure arid size after a sheather\'s floating and an auramine-phenol and acid-fast-staining.

从某奶牛场分离出隐孢子虫卵囊，用金胺酚-改良抗酸染色及饱和蔗糖漂浮后，通过显微镜检，根据其形态、结构、大小等特性鉴定为鼠隐孢子虫。

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。

Nevertheless, the mosquitoes provide a physiological milieu, for sporogony of the malaria parasites.

已知蚊虫天然免疫系统在疟原虫穿壁、卵囊发育和子孢子移行进腺等过程中产生包括局部和全身性多位点的免疫反应，同时蚊虫为疟原虫孢子生殖阶段提供必不可少的生理环境。

Spore density had a significant positive correlation on the colonization of different structure, colonization intensity was very significantly correlated with soil organic matter and soil available P, arbuscule abundance had a significant negative correlation with soil available P, spore density had a positive correlation on soil available P.

孢子密度与AM真菌各项指标均呈极显著正相关；侵染强度与有机质和速效磷呈极显著正相关；丛枝丰度与速效磷呈极显著正相关；泡囊丰度与有机质呈极显著正相关，与速效磷呈显著正相关；孢子密度与速效磷呈显著正相关。

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。

A unisexual reproductive structure of gymnospermous plants such as conifers and cycads, typically consisting of a central axis around which there are scaly, overlapping, spirally arranged sporophylls that develop pollen-bearing sacs or naked ovules or seeds.

球果单性裸子植物的生殖器，例如针叶树和铁树目植物，一般由覆满鳞片和褶皱的中心轴构成，长螺旋状排列的孢子叶，孢子叶最终成为花粉囊或裸露的孢子或种子

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。

Molecular studies have identified some genes participating in this process, including those regulating anther cell division and differentiation, controlling male meiosis, supporting pollen development, and promoting anther dehiscence.

分子生物学的研究已经发现了一些参与这一过程的基因，包括控制花粉囊组织的分化、小孢子母细胞的减数分裂、小孢子的发育和花药的开裂等。

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！
