| 单词 | 生命循环 |
| 释义 | 〔merozoite〕A protozoan cell that arises from the schizogony of a parent sporozoan and may enter either the asexual or sexual phase of the life cycle.裂殖子：亲本孢子虫通过裂殖法产生的原生动物细胞，能开拓新的无性或有性生命循环〔adolescent〕The adolescent grows up to become the adult.The wordsadolescent and adult that refer to these two stages in the human life cycle ultimately come from forms of the same Latin word, adolēscere, meaning "to grow up.” The present participle ofadolēscere, adolēscēns, from which adolescent derives, means "growing up,” while the past participleadultus, the source of adult, means "grown up.” Appropriately enough,adolescent, first recorded in English in a work written perhaps in 1440, seems to have come into the language beforeadult, first recorded in a work published in 1531. 青少年成长为成年人。adolescent 及 adult 这两个词都表示人类生命循环中的两个阶段，并且始终都来自于同一个拉丁词 adolescere 的不同形式，意为“成长”。 现在分词形式的adolescere--adolescens 产生出 adolesent ，表示“正在成长的”， 而其过去分词adultus 则为 adult 的语源，意为“已经长大的”。 很恰当地是，adolescent 约于1440年首次用于英语作品中， 似乎比首次于1531年刊登在一作品中的adult 一词要早出现在英语语言中 〔hydroid〕The asexual polyp in the life cycle of a hydrozoan.水螅虫类：生命循环中的无性生殖水螅虫〔hydromedusa〕A hydrozoan in the medusoid stage of its life cycle.水母：一只在生命循环期间处于水母阶段的水螅虫〔hydroid〕Any of numerous characteristically colonial hydrozoan coelenterates having a polyp rather than a medusoid form as the dominant stage of the life cycle.水螅虫：许多典型的移居的腔肠动物中水螅虫类的任何一种，在生命循环中最重要阶段以水螅的形状而不是水母的形状出现〔haplont〕An organism that is haploid throughout its life cycle except as a zygote, when it is diploid, as in many algae and fungi.单元体：一种在其整个生命循环过程中保持单倍体，而只有在海藻或真菌中作为合子才呈现二倍体状态的生物组织〔jellyfish〕Any of numerous usually free-swimming marine coelenterates of the class Scyphozoa, characteristically having a gelatinous, tentacled, often bell-shaped medusoid stage as the dominant phase of its life cycle.水母，海蜇：大量的、经常自由游动的真水母类腔肠动物，胶质的、带有触须的、常为钟形的类水母体阶段是其生命循环中的主要形式 |
