Ultrastructure of Synergids in Mature Embryo Sac of Convolvulus arvensis

Sun Fu-sheng   

Abstract: The main ultras tructure of synergids in mature embryo sac of Convolvulus arvensis L. was studied by means of electron microscope was the same as those previously reported. However, growth of many finger-like projections continuously distributed on the outer surface of synergids was observed. Exchange of material between central cell and synergids was enhanced by the transfer wall. The profile of endoplasmic reticulum which was long and parallelly arranged became shortened and randomly expanded. A narrow path appeared at the junction of egg and synergid.

Key words: Convolvulus arvensis, Synergid, Finger-like projections
