Abstract
Evidence from light and electron microscopy shows that symbiotic algae occur in a large percentage of fertilized eggs of two strains of green hydra. Transmission of algae to eggs may occur by insertion of algae-laden endodermal cell processes across the mesogloea into the ooplasm of the ectodermally-derived egg when oocyte maturation is well under way. This transmission mechanism is contrasted with mechanisms postulated for other strains of green hydra.
摘要
光学显微镜和电子显微镜提供的证据表明，共生藻类存在于两种绿螅菌株的大部分受精卵中。当卵母细胞成熟进行得很顺利时，藻类可能通过充满藻类的内胚层细胞突起穿过中胶层插入外胚层来源的卵的卵质中，从而传递给卵。这种传递机制与其他绿螅菌株所假定的机制形成对比。
