高中《生物》（必修）新教材的第三章写道:“受精卵是一个细胞。这个细胞经过细胞分裂、组织分化和器官形成,直到发育成新个体,这就是生物的个体发育。”（见教材109页）这一定义强调了“受精卵→新个体”这一“胚的发育”（或“胚胎发育”）阶段,而忽略了“幼体→成体”这一“胚后发育”阶段,这是不妥的。 为了保证生物学概念的科学性、严谨性和完整性,本人参照《简明生物学辞典》进行了适当修改:“多细胞生物体从受精卵开始,经细胞分裂、组织分化、器官形成、直到性成熟的整个
The third chapter of the new textbook for high school “Biology” (required) states: “A fertilized egg is a cell. This cell undergoes cell division, tissue differentiation, and organ formation until it develops into a new individual. This is the biological development of the organism.” See page 109) This definition emphasizes the “embryo development” (or “embryonic development”) stage of “fertilized egg → new individual” and ignores the “embryo development” stage of “larvae → adult”. This is wrong. In order to ensure the scientificity, rigor and integrity of the biological concept, I have made appropriate modifications based on the “Concise Dictionary of Biology”: "Multicellular organisms start from fertilized eggs and undergo cell division, tissue differentiation, organ formation, and sexual activity.
