After the observation on the development of Enteromorpha prolifera(Müller) J.Ag.by microscope and the paraffin-section method,the microscopic characteristics of the develop process from spores to mature thalli have been expatiated.Spores of Enteromorpha prolifera(Müller) J.Ag.were developed from mature thallus cells,every mature thallus cell could release 10~30 spores.Every spore divided into 2-cell structure after the first division,and this structure had obvious polarity.The base-cell developed into rhizoid,and the top-cell formed protonema by horizontal-division continually.Pipelike thallus was formed by vertical-division of the middle protonema cells,and top-cell kept horizontal-division.Vertical-division included tangential-division and radial-division,tangential-division made the pipelike thallus more thick,and radial-division made the branch formed.The internal cavum of pipelike thallus contained villiform protuberances and meshwork structures which were composed of glycoprotein.When the number of cells in cross section of pipelike thallus reached 30~50,the villiform protuberances disappeared and the meshwork structures became tight,then the mural cells of pipelike thallus adhered and the foliolose thallus formed.The total developmental process of Enteromorpha prolifera(Müller) J.Ag.kept polarity.
