多细胞的

More calcium precipitates were located in the epidermis, endothecium and tapetum of the sterile anther than in those of the fertile anther. Longitudinal inner cell wall of the sterile anther became thicker than that of the fertile anther at the dyad stage and uninucleate pollen stage.

到四分体与单细胞花粉时期，不育花药的木质部细胞的次生加厚壁上有较多的Ca2+沉淀，连接组织中的Ca2+沉淀也大大增加，所有不育花粉外壁较厚而发育都不正常。

Just as a general egg cell differentiates through epigenesis to become a legion of specialized cells, so in evolution animals and plants split up into varieties more dependent on narrower niches.

正像一个普通的卵细胞经过后来的渐变分化成众多不同的专门细胞，在进化中，动植物也分化成更多不同的种类，各自适应一个更窄的生态龛。

The structures of the two-year-old tap roots are similar to that of the one-year-old ones, while the periderm thickness is increased. In the secondary xylems of the two-year-old roots, the woody fibers are distributed in groups and the interxylary phellem appears. The vascular rays are multiseriate. Phellem cells surround a sclereid form the phellem cycle in the phloem nearby the periderm.

二年生黄芩主根的主要结构与一年生的基本相同，其不同之处为：二年生主根的周皮增厚，次生木质部中木纤维成群分布，出现木间木栓；维管射线为多列且明显；在近周皮的韧皮部内出现包围石细胞的木栓环组织。

In thistreatment,some embrocyte,which may originate from the nucellus cell,can be foundin few of ovaries in APⅣ.The embryos in most of ovaries in APⅣ and IR36develop normally,but the endosperm,in which many crystal-like substances wereobserved,by spike-spray with 2,4-D 3-hours after pollination.

少数APⅣ子房的"腔"内出现多个"胚状体"，推测可能来自珠心细胞的分裂；在受精后处理的大部分子房胚胎发育正常，但胚乳发育却不正常，胚乳内观察到许多的结晶体。

The Benson-Calvin cycle is restricted to the BS cells, minimizing photorespiration and allowing increased carbon, nitrogen, and water use efficiency.

在本森，卡尔文循环的限制细胞的学士学位，尽量减少光呼吸和使更多的碳，氮和水的使用效率。

The injury to intestinal mucosal immunity ,in addition to increased intestinal permeability, allows bulk of intestinal toxic substance to enter blood and displacement of intestinal bacterium causing,pyemia ,followed by multi-organ dysfunction syndrome.

另一方面辐射造成肠道粘膜免疫细胞的损伤，使其功能抑制，加之肠道机械屏障损伤所致的肠道通透性增加，肠道内大量毒性物质入血，细菌移位，造成严重的肠源性感染，继发多器官功能不全，后者是急性放射病抢救失败的重要原因之一。

It is becoming more clear that tumor progression is not exclusively regulated by oncogene and tumor suppressor gene pathways.

肿瘤的演进是一个复杂的多步骤的过程，包括正常细胞的恶性转化、肿瘤的生长、侵袭和转移。

But to make a true clone a cell needs to be not just pluripotent, but totipotent and thus able to turn into an entire animal.

但是为制作真正的克隆，一个细胞不仅要是多功能的，还必须是全能的，进而能转化成完整的动物。

A multicellular organism of the kingdom Animalia, differing from plants in certain typical characteristics such as capacity for locomotion, nonphotosynthetic metabolism, pronounced response to stimuli, restricted growth, and fixed bodily structure.

动物动物界中的多细胞生物，某些典型特征与植物不同，如有运动能力，能进行非光合作用的新陈代谢，能对刺激产生有声反应，有限制的生长和固定的身体结构

Surface waxes of the pericarp were observed by scanning electron microscopy; the structure and composition of cell wall were studied using light microscopy, transmission electron microscopy and Fourier transform infrared microspectroscopy respectively; the changes of calcium in the cell wall were determined by atomic absorption and the integrity of cell membrane by conductivity meter respectively.

本论文采用扫描电子显微镜研究果实表皮蜡层的变化，用光学显微镜、透射电子显微镜和傅里叶变换红外光谱仪研究果实细胞壁结构和成分的变化，用原子吸收分光光度计测定细胞壁钙离子的变化，用电导率仪检测果实细胞的完整性。同时测定了果实酚类物质含量、多酚氧化酶(EC 1.10.3.1)活性、过氧化物酶(EC 1.11.1.7)活性，并分析了果实硬度、糖和酸含量等品质指标。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
