Many free ribosomes synthesized numerous proteinous particles and formed yolk granules without membranes by aggregation and fusion of themselves ;

丰富的游离核糖体合成了大量致密的蛋白质颗粒并在卵质中直接聚集融合成无 膜 的 卵黄粒；

And the dense proteinous particles synthesized by these free ribosomes could be accumulated and developed directly in ooplasm into yolk granules without membranes .

游离型核糖体率先参与内源性 卵黄合成形成无 膜卵黄粒。

They may be soluble ( those in egg yolk and Blood plasma ) or insoluble ( those in cell membranes ) in water and water solutions .

有的可以溶解于水和水溶液（在 蛋黄和血浆中的）有的则不能溶解（在细胞 膜中的）。
