In this article we will discuss about the evolutionary trends in the development of plant body in the chlorophyta. i. Evolution of Sexuality in the Chlorophyta: The Chlorophyta represent an evolutionary series in which the gametic union became most firmly established even in the most primitive forms and persists among the highest members of the series. The evolution in sexuality [...]
In this article we will discuss about the classification of ulotrichales. Family Ulotrichaceae: Plants are filamentous: Filaments are with or without an attaching base; typically unbranched, composed of cylindrical uniseriate cells with thin to gelatinous walls. Cells possess lateral plate-like or band-like chromatophores with or without pyrenoids. Asexual reproduction is by bi- and quadriflagellate zoospores, although a few genera (e.g., [...]
In this article we will discuss about the reproduction in basillariophyta. This will also help you to draw the structure and diagram of reproduction in bacillariophyta. Diatom cells multiply usually by a peculiar method of cell division. An increase in the volume of the frustule results in a slight separation of the valves which is followed by mitotic division of [...]
