Another, they're releasing reproductive cells called spores.

后来，它们又一种叫做子的生殖细胞。

Their hardy spores sport thick cell walls that allow them to survive extreme temperatures.

它们坚韧的子具有厚厚的细胞壁，可以在极端温度下生存。

But when the baby grows up, the cells inside its capsule create spores, which are released to the wind.

但当小宝宝长大后，胶囊内的细胞会产生子，这些子会被到风中。

But instead of having seeds, these plants reproduce by releasing tiny, single-celled spores.

但是这些没有种子，而是通过小的单细胞子进行繁殖。

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

例如，蕨类从子中繁殖，它们的生殖细胞需要潮湿的环境才能相互接触。

Like, they all create spores, single cells coated in a super tough, armor-like molecule that are an integral part of the bryophyte life cycle.

比如，它们都会产生子，单细胞被一层超级坚硬的盔甲状分子包裹，这是苔藓生命周期中不可或缺的一部分。

Many people with AIDS die from infections that a healthy immune system would typically be able to fend off, like pneumocystis, cytomegalovirus, or mycobacterium avium complex.

许多艾滋病患者死于原本健康的免疫系统本可抵抗的感染，比如卡氏肺子菌、巨细胞病毒或鸟分枝杆菌复合。

Airborne allergens like pollen, dust, animal hair, or mold spores cause mast cells in the tissues to release histamine, causing the eyes and nose to become inflamed and watery.

花粉、尘土、动毛发、霉菌子等空气传播的过敏原通过促进组织中的肥大细胞组胺，最终导致眼睛和鼻子的炎症和水肿。

Each sporozoite produces as many as 30,000 mature parasite cells called merozoites, which spread through the bloodstream, burrow into red blood cells, and cause a full-blown infection.

每个子子产生多达 30, 000 个称为裂殖子的成熟寄生虫细胞，它们通过血液传播， 钻入红细胞， 并引起全面感染。

Matrix producers pump out the extracellular goo, swimmers assemble flagella and are free to move about or migrate, and spore-formers produce dormant, tough endospores that survive starvation, temperature extremes, and harmful radiation.

基质制造者能够分泌细胞外粘性质，鞭毛可以自由活动和迁移，芽菌生产休眠、坚硬的子内壁，子内壁能够在饥饿、极端温度、以及有害射线下生存。

Sentence 73 These plants propagate by producing spores—-tiny fertilized cells that contain all the instructions for making a new plant—-but the spores are unprotected by any outer coating and carry no supply of nutrient.

这些通过产生子来繁殖——子是一些小的已受精细胞，它们携带了生成一株新的所有指令信息——但是子没有任何外部表皮的保护，也没有营养供应。

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，否则子将无法生长——它们所含的不同生殖细胞需要在表面覆盖一层薄薄的水才能四处移动并聚集在一起。
