n.胞胚；囊胚

The cells of the blastula, called blastomeres, also each receive a full diploid set of chromosomes. 這些囊胚細(xì)胞，稱卵裂球，每個(gè)細(xì)胞都有一套二倍體染色體組。

Cleavage produces a blastula, a sheet of cells rounded into a sphere that in most species surrounds a cavity. 卵裂產(chǎn)生一個(gè)囊胚，形成的細(xì)胞壁球形排列形成一個(gè)空腔。
