- W1972253732 abstract "H. angulata is a scale‐covered, asymmetrical green unicell with two laterally attached, anisokont flagella. In recent years it has been classified in the Prasinophyceae. The flagellar apparatus replicates, and the cell begins to cleave at the side opposite the flagella before the nucleus can be perceived to be in prophase. The flagellar apparatuses separate, and the extra‐nuclear development of the spindle occurs from the regions occupied by rhizoplasts. Rhizoplasts or partial rhizoplasts lie at the flat metaphase spindle poles. By metaphase, the cell has already elongated to the extent that it is nearly twice as long as at interphase. The spindle and the cell itself elongate greatly during anaphase with a concomitant further separation of the flagellar pairs. Although the interzonal spindle persists during cytokinesis as in charophycean algae, H. angulata is similar in flagellar scale morphology and other characteristics to the chlorophycean Platymonas , which has a collapsing interzonal spindle at telophase, a phycoplast, and a wall‐like theca, which develops by the fusion of small stellate scales. It is hypothesized that the collapsing telophase spindle and phycoplast evolved in green flagellates similar to Platymonas , in which cell and spindle elongation became restricted by a cell wall that evolved from stellate scales similar to those in Heteromastix. Such walled flagellates are then visualized as having eventually given rise to Chlamydomonas and to the entire range of chlorophycean algae with phycoplasts. It is pointed out that the hypothesis has a number of implications by which its validity could be judged when sufficient information becomes available." @default.
