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——被带到个物上的花粉在磁性胚珠上授来结成新种子——才会发生。

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，下个过程才会发生————物上带过来的花粉使个雌性胚珠，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.

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

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在同个子房内，也将遵循有利于它们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.

在某些整群物中， 胚珠直立，而在些物群中， 胚珠则悬空；在少数物的同个子房内， 个胚珠占据前者的位置， 第二个胚珠占据后者的位置。
