Drench coccus is mixed by film of oar of karyoplasm, cell, cell cellular wall form. 淋球菌由核质、细胞浆、细胞膜和细胞壁等构成。
But zygote at dormancy stage has a small nucleolus, suddenly decreased karyoplasm and low density of ribosome which indicate an obvious decline in metabolism. 休眠期的合子核仁变小，核质急剧减少，细胞质中核糖体密度下降，细胞代谢活性明显降低；
karyoplasm(nucleoplasm) 核质, 核浆, 非染色质物质
