Another, they're releasing reproductive cells called spores.

后来，它们又释放一种叫做孢子的生殖细胞。

Its stable temperature and high density help preserve and disperse reproductive cells.

稳定的温度和较高的密度有助于保存和分散生殖细胞。

Work is already under way to develop principles for editing reproductive cells.

编辑生殖细胞的原则制定工作已经开始。

However, each reproductive cell has only 23 individual chromosomes.

然而，每个生殖细胞只有 23 条独立的染色体。

Ferns, for example, reproduce from spores and need damp environments for their reproductive cells to reach each other.

例如，蕨类植物从孢子中繁殖，它们的生殖细胞需要潮湿的环境才能相互接触。

The idea that one scientist could make the leap towards editing reproductive cells has been condemned, but it has not been ruled out.

一位科学家可在编辑生殖细胞方面取得很大进步的这种观点遭到谴责，但并没有被完全否定。

Like, when you're facing a life-or-death ordeal, you don't need to be digesting that cashew cluster in your intestines, or producing reproductive cells, or fighting off an infection.

比如，当你面临生死攸关的考验时，你不需要消化肠道里的腰果，或者产生生殖细胞，又或者抵抗感染。

This meant that they were really  dependent on a wet environment, otherwise the spores would fail to grow - the  different reproductive cells they contained needed a thin layer of water on the plant's  surface to move around and come together.

这意味着它们确实依赖于潮湿的环境，否则孢子将无法生长——它们所含的不同生殖细胞需要在植物表面覆盖一层薄薄的水才能四处移动并聚集在一起。
