FINE STRUCTURE OF MITOSIS AND CLEAVAGE IN <i>FRIEDMANNIA ISRAELENSIS</i> (CHLOROPHYCEAE: CHLOROSARCINACEAE)¹

Abstract

ABSTRACT Observations on the ultrastructure of Friedmannia israelensis Chantanachat &amp; Bold revealed the presence of a phycoplast and zoospores with cruciate rootlets. During mitosis, the nuclear envelope partially disintegrates and the basal bodies remain at the cell surface on either side of the developing cleavage furrow. The events during mitosis and cleavage in Friedmannia resemble those reported in the other green algae, Platymonas and Pleurastrum .
