植物的受精卵是一个胚性细胞,在这个细胞中具有一整套来自双亲的遗传基因,当受精卵进行分裂时,染色体进行复制,分成为两个子细胞,两个子细胞含有和受精卵同样的遗传基因。这样不断分裂形成了千百万个子细胞。在正常的情况下,分裂过程不仅是细胞数量的增加,而且各部位的细胞进行分化,产生出不同的组织和器官,最后形成完整的植物体。因此,从理论上讲,无论哪一个器官和组织的细胞,都应该具有全套的遗传基因,在遗传上具有全能性, The plant’s fertilized egg is an embryogenic cell in which a set of genes from the parents are involved. As the fertilized egg divides, the chromosome is replicated and divided into two daughter cells, both of which contain the same inheritance as the fertilized egg gene. This split into millions of sub-cells. Under normal circumstances, the process of division is not only an increase in the number of cells, but also the differentiation of cells at various sites to produce different tissues and organs, and finally the formation of a complete plant body. Therefore, in theory, no matter which organ and tissue cells should have a complete set of genetic, genetically versatile,
