Yes, majority of algae are unicellular. 2004). Green algae on the other hand provide a source of food for the zooplankton to grow and flourish. Most green Algae are unicellular e.g. One common example of a unicellular algae is the green algae Prototheca. OYEs from unicellular green algae: two birds with one stone. R Y Stanier , R Kunisawa , M Mandel , G Cohen-Bazire Microbiology and Molecular Biology Reviews Jun … Brendan Gow. Green algae can be unicellular (having one cell), multicellular (having many cells), colonial (many single cells living as an aggregation), or coenocytic (composed of a large cell with no crossed walls; the cell can be uninucleated or multinucleated). Epub 2013 Apr 5. Algae also lack true roots, stems, and leaves—features they share with the avascular lower plants (e.g., mosses, liverworts, and hornworts). Algae can be unicellular, live in colonies, or even be multicellular.The wide variety algae makes them hard to classify. Green algae live in salt and fresh water, on land, on the surface of trees, stones or buildings, in damp, shaded places. The picoplankton green algae Micromonas commoda and Ostreococcus tauri contain a 3/3 Glb with some features similar to land plant Glbs, such as a conserved Phe B10 and proximal and distal His residues situated at identical positions (Fernández et al. Algae are small unicellular organisms whereas cyanobacteria are multi-cellular organisms and larger in size. Whereas C. reinhardtiidisplays a genome complexity approaching that of Arabidopsis, some recently characterized microalgae may have genomes simpler than that even of yeast. Algae Definition. The genomes of certain green algae and red algae (rhodophytes) encode single‐domain Glbs (Vinogradov et al., 2013). 2013 Sep;93(12):3133-6. doi: 10.1002/jsfa.6114.
