植物的生殖器官由雌蕊与雄蕊组成。其中,花粉由雄蕊产生。花粉壁覆盖着成熟的花粉,起到保护花粉免受外界病虫侵害、抵御干燥、紫外线辐射以及授粉识别等作用。在人类文明进程中,英国植物学家尼西米·格鲁(Nehemiah Grew)在1682年编写的《植物解剖学》一书中首次对花粉做出了“生殖性小球体”的简短评述,也正是这一小步开启了历史上人们 The plant’s reproductive organs consist of pistils and stamens. Among them, pollen is produced by stamens. The pollen wall is covered with mature pollen, play a role in protecting pollen from external pests and diseases, resist drying, ultraviolet radiation and pollination recognition. In the process of human civilization, the British botanist Nehemiah Grew made the first brief review of pollen in “Plant Anatomy” written in 1682 , It is also this small step to open the history of people
