胚基的

When the pollen tube comes into the micropyle and contact one of the synergids, both synergids do not show any sign of degeneration.

在二细胞原胚的顶细胞和基细胞中，均可观察到与合子中形态相似的双亲质体和线粒体。

The ovule of development is the one nucellus that make a group at first organization, because basilar segmentation is rapidder and form or two bags by the layer, bead by , other nucellus the organization laps inside and next alveolus stays in one aspect of the matter, bead aperture .

发育的胚珠最初是一整团珠心组织，由于基部的细胞分裂较快而形成一层或两层包被层—珠被，将其他珠心组织包裹在内并在一端留下一个小孔—珠孔。

Ovary entire,(2 or)3-carpellate, 1-locular; ovules many, on parietal to basal placentas; style inserted at apex of ovary, persistent; stigma punctiform.

全缘的子房，(2或)3具心皮，1室；胚珠很多，侧膜胎座到基生胎座；花柱着生的在子房先端，宿存；柱头点状。

Leaves 1--3, linear to orbicular-ovate, base usually narrowed into a petiole; ovary base often constricted into a short stipe; ovules 1 per locule.

叶1 --3，卵形线形的到圆形，基部通常缩小成为叶柄；子房基部通常缢缩的成为一短柄；胚珠1每室。

Carpels numerous, inserted on short receptacle; ovule ascending from base of locule; style subterminal, erect, deciduous.

心皮多数，着生于短花托；胚珠子房室的上升的自基部；花柱近顶生，直立，落叶。

Inflorescences mostly lax, rarely capitate, always without clearly defined involucral bracts; ovules basal, anatropous.

多数疏松，很少头状的花序，总是没有明显确定的总苞片；基部的胚珠，倒生。

At the end of February, the bract attained approximately their full size, and a pair of anatropous ovules were initiated on the adaxial surface at the base of the fertile ovuliferous scale.

2月底，苞片体积不再发生变化，珠鳞膨大端的基部的近轴面分化出2个倒生胚珠。

Ovaries 2, free or basally connate; ovules 2-6, biseriate on each side of a prominent placenta.

子房2，离生或基部合生；胚珠2-6，在一突出的胎座的每边双列。

At skin sites destined to have apocrine units, a third epithelial bud develops from the opposite side of the follicle above the level of the sebaceous gland anlage.

在形成顶泌汗腺单位的皮肤部位还有第三个上皮胚芽形成，它发生于皮脂腺始基之上与毛囊相对的位置。

Head and tail of fold formed gradually to bend and further embryo body is "C", where has appeared in measurements neural tube closed, 1, 2, 3, to bow, the inner ear or one of the nest also hear clearly visible.

谢谢！！！！！第四周（发生第10-13期）头褶及尾褶的形成使胚体逐渐弯曲并进一步呈&C&形，神经管在体节出现处已闭合，第一、二、三、对腮弓相继出现，内耳的原基听窝也清晰可见。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
