In this article we will discuss about the general features and phylogenetic relationships of euglenophyta. General Features of Euglenophyta: The Euglenophyta represent mostly unicellular naked motile individuals which usually occur in fresh-water. Some species form dendroid colony. The thallus possesses a definite nucleus and the grass-green colour is due to the presence of chlorophyll localized in chromatophores. Few species lack [...]
In this article we will discuss about the classification of cladophorales. Family Cladophoraceae: This family contains many fresh-water forms. Some of the large genera, such as Cladophora, have both fresh-water and marine representatives, but there are several strictly marine genera. The plants are composed of multinucleate cells arranged in uniseriate fashion in simple or branched filaments. The chloroplast is parietal [...]
