在这些物种中,受精卵发育为雌性,未受精卵发育为雄性。
In these species, fertilized eggs develop into females and unfertilized eggs into males.
由受精卵发育而来,包括基足、柄和孢蒴。
It develops from the zygote and comprises the foot, seta, and capsule.
抑制水中的细菌生长,使受精卵发育成健壮的胚胎、幼虫、幼苗。
Laser can inhibit the growing of bacteria in the water and help the zygote to grow into a stronger embryo, larva, and seedling.
During development of the embryo it goes from being a single cell, the fertilized egg, to being a multi-cellular organism with billions of cells in it.
胚胎的发育,始于一个单一细胞,即受精卵,直到形成一个以十亿计数量的细胞构成的,多细胞有机体
Cells that are within the region that becomes the nervous system become less like the zygote and more like the cells of our brain, neurons and glia, and cells of the mature brain.
位于神经发育区中的细胞,变得越来越不像受精卵,而像脑细胞,神经细胞或神经胶质细胞等等,这些成熟的脑组织中细胞
All of the cells that are reproduced during development are the same in certain ways, they contain the same DNA, they're all progeny of the same fertilized egg, but differences are acquired within specific cell populations during the process of development.
所有在发育过程中繁殖的细胞,在某些方面都是一样的,它们都有相同的DNA,都是同一个受精卵的后代,但是分化是在特定细胞类群,发育过程中必不可少的
