1.Only after pollination can the next process occur-fertilisation-when the pollen carried from another plant fertilises a female ovule to make new seeds.

只有经了授粉，下一个程序受精——被到另一个植物的花粉在磁性胚珠授精来结成新种子——才会发生。

2.The pollen collected in the stigma travels through the stile and fertilizes the ovules in the ovary.

在柱头的花粉穿花柱, 使卵巢的卵子受精。机翻

3.Only after pollination can the next process occur – fertilisation - when the pollen carried from another plant fertilises a female ovule to make new seeds.

只有在授粉之后，下一个程才会发生——受精——从另一株植物来的花粉使一个雌性胚珠受精，从而产生新的种子。

4.In the latest study, the team used micro-CT technology to scan the fossil and found that the interior contained inverted ovules, which is a key feature for determining angiosperms.

在最新的研究，该团队使用微型 CT 技术扫描化石，发现内部包含倒置的胚珠，这是确定被子植物的关键特征。

5.There must sometimes be a physical impossibility in the male element reaching the ovule, as would be the case with a plant having a pistil too long for the pollen-tubes to reach the ovarium.

有时雄性成分到达胚珠在物理是不可能的， 例如雌蕊太长以至于花粉管无法到达子房的植物就是这种情况。机翻

6.If so, the position of the ovules, even when one is erect and the other suspended within the same ovarium, would follow the selection of any slight deviations in position which favoured their fertilisation, and the production of seed.

如果是这样， 胚珠的位置， 即使一个直立而另一个悬置在同一个子房内，也将遵循有利于它们受精和种子生产的任何轻微位置偏差的选择。机翻

7.In certain whole groups of plants the ovules stand erect, and in others they are suspended; and within the same ovarium of some few plants, one ovule holds the former and a second ovule the latter position.

在某些整群植物， 胚珠直立，而在另一些植物群， 胚珠则悬空；在少数植物的同一个子房内， 一个胚珠占据前者的位置， 第二个胚珠占据后者的位置。机翻
