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 [...]
The following points highlight the three families under which chlorellaceae has been classified. The families are:- 1. Chlorellaceae 2. Coelastraceae 3. Hydrodictyaceae. Family # 1. Chlorellaceae: This family includes the unicellular non-motile genus Chlorella which is a tool of many physiological experiments. It reproduces by the development of non-motile spores. Genus Chlorella: This unicellular alga has a very varied habitat. [...]
