Abstract
Fertilization of red algae is achieved by fusion of a spermatium and a trichogyne, the specialized process of a carpogonium(egg cell). Recently, studies of red algal fertilization have been carried out using species suitable for detailed observations and experimental research. These studies revealed ultrastructural and histochemical properties of spermatium and trichogyne that are responsible for the specific attachment between non-motile gametes during fertilization. The process of the fertilization also includes some cellular events, i. e., resumption of spermatial nuclear division and cell wall formation. These events are induced by gamete attachment and followed by cytoplasmic and nuclear fusion between gametes. There are significant variations in the morphological and histochemical features of gametes and processes of fertilization among red algae. To understand how such considerable variety of fertilization mechanisms has occurred during evolution of red algae, detailed, comparable information in a wide range of taxa is necessary.
