Ultrastructural studies on the corticating filament of Chara zeylanica

Abstract

The morphology of charophytes have developed curiosity in many researchers to fully understand their cell structure, physiology, biochemistry and phylogeny. In this regard, a number of studies on the ultrastructure of the internodal cell of corticate and ecorticate members of charophytes have been carried out. Although there are several studies on the internodal cells, there are no detailed investigations on the ultrastructure of corticating filaments of the genus Chara. Hence, this paper focuses on the ultrastructural study of the corticating filaments of Chara zeylanica, observed under transmission electron microscope, along with the ultrastructure of the internodal cell. The study revealed the presence of charosomes on the cell wall of the corticating cells along with other cell inclusions such as amitotic nucleus, chloroplast, mitochondria, glycosome, echinoid bodies, lipids, endoplasmic reticulum and crystalline inclusions.
