细胞分裂

In seed plants also produce spores, and spores are profiled in the ovule Pearl hearts a megaspore mother cell produces large spores by meiosis in the anthers of the microspore mother cells produced by meiosis of microspore.

在种子植物中也产生孢子，且均为孢子异型，在胚珠的珠心中的1个大孢子母细胞经减数分裂产生大孢子，在花药中的小孢子母细胞经减数分裂产生小孢子。

Small cell of the mother after the cytoplasm of simultaneous type, tetrad of epidermis, mature pollen of two cell types.

小孢子母细胞减数分裂后胞质分裂为同时型，四分体为四面体型排列，成熟的花粉粒为二细胞型。

Rbkinesin-6 plays an important role in telophase/cytokinesis phase, Rbkinesin-6 ablation can inhibit the growth of lung cancer cells.

Rbkinesin-6在A549细胞有丝分裂末期／胞质分裂最后阶段起重要作用，Rbkinesin-6基因沉默可以抑制肺癌细胞的生长，为肺癌基因治疗的研究提供了新的思路。

Rbkinesin-6 ablated cells could not finish the telophase/cytokinesis phase, and became binuclear/multinuclear cells.

Rbkinesin-6缺失的细胞无法完成有丝分裂末期／胞质分裂，进而转变为双／多核细胞。

The results showed that the changes of the types were not caused by new cell mutation, but by translocation of the different cell types of variegation. The changes of division direction of white cells and green cells resulted that some of the green epidermal cells translocated into the second layer and it pushed furthermore the origin white cells of the second layer into the third layer, so that the variegation altered.

Pollock'突变型异化不是由于细胞突变形成，而是由于质体突变型白色细胞和原型绿色细胞在生长发育过程中相互竞争转轨所致，即白色细胞和原型绿色细胞改变了分裂方向，部分表皮绿色细胞进人第二层，挤压第二层白色细胞转轨进人第三层，导致细胞类型的移位，从而形成异型斑。

Though the gametic nucleus of normal cell didn't enter the amicronucleate cell, there were cytoplasm and organelle exchanges between two cells.

在接合对中，有小核细胞一方可以完成正常的减数分裂过程，既有配子核的形成、配子核的融合、配子核分裂，最终形成两个有小核的子细胞。

Results: PC12 cells exhibited amitotic figures including circular shrink, sideways concave, etc.The figures of asymmetric division in shape, size and the cell chemical properties by staining and the cell enucleation were observed.

结果：PC12细胞呈现横缢型和侧凹型等无丝分裂像，并且观察到其形态、大小和化学性质的不对称性分裂及细胞脱颖现象。

The development of Peiai 64S and IR36 did not differ up to microsporocyte formation stage; but since meiosis stage, male reproductive cells of Peiai 64S underwent several structural changes and ultimately terminated by early bicellular stage.

结果表明，小孢子母细胞减数分裂之前，培矮64S与IR36的发育过程基本相似。但从减数分裂开始，培矮64S的雄性性细胞出现一些异常变化，并最终发育至二胞花粉早期败育。

Methods Cell cultures were harvested and stained with haematoxylin and eosin,to analyze cellular metaphase morphology.

收获细胞经苏木素和伊红染色，观察分裂中期细胞核形态，计算核极分裂象细胞百分比。

Cultured cells were harvested and stained with haematoxylin and eosin to analyze cellular metaphase morphology.

收获细胞经苏木素和伊红染色，观察分裂中期细胞核形态，计算核多极分裂像细胞百分比。

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。
