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，程序受精——被带到另植物上的花粉在磁性胚珠上授精来结成新种子——才会发生。

只有在授粉之后，程才会发生——受精——从另株植物上带来的花粉使雌性胚珠受精，从而产生新的种子。

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，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。

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，而在另些植物群， 胚珠则悬空；在少数植物的同子房内， 胚珠占据前者的位置， 第二胚珠占据后者的位置。

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， 即使直立而另悬置在同子房内，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。
