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

只有经过了授粉，下个程序受精——被带个植物上的花粉磁性胚珠上授精来结成种子——才会发生。

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

柱头中收集的花粉穿过花柱, 使卵巢中的卵子受精。

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

只有授粉之后，下个过程才会发生——受精——从株植物上带过来的花粉使个雌性胚珠受精，从而产生的种子。

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.

的研究中，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。

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.

有时雄性成分达胚珠物理上是不可能的， 例如雌蕊太长以至于花粉管无法达子房的植物就是这种情况。

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， 即使个直立而个悬置同个子房内，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。

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.

某些整群植物中， 胚珠直立，而些植物群中， 胚珠则悬空；少数植物的同个子房内， 个胚珠占据前者的位置， 第二个胚珠占据后者的位置。
