These lipids are pin shaped molecules whose heads are attracted to water, and tails are repulsed by it.

脂质是呈大头针状的分子，头部具有亲水性，尾部具有疏水性。

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，它产生孢子，单细胞被一层超级坚硬的盔甲状分子包裹，是苔藓植物生命周期中不可或缺的一部分。
