Algae
Algae (; singular alga ) is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades. Included organisms range from unicellular microalgae, such as ''Chlorella,'' ''Prototheca'' and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to in length. Most are aquatic and autotrophic (they generate food internally) and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem that are found in land plants. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the ''Charophyta'', a division of green algae which includes, for example, ''Spirogyra'' and stoneworts. No definition of algae is generally accepted. One definition is that algae "have chlorophyll ''a'' as their primary photosynthetic pigment and lack a sterile covering of cells around thei ...

Mesotaeniaceae
The Mesotaeniaceae are a small family of unicellular green algae known as the "saccoderm desmids". The Mesotaeniaceae appear to be sister or ancestral to the Zygnemataceae. The desmids are a deep branching group of Zygnemataceae. ''Spirotaenia'' was found to be a basal green alga. Genera The Mesotaeniaceae includes the following genera: * ''Ancylonema'' Berggren, 1872 * ''Cylindrocystis'' Meneghini ex De Bary, 1858 * '' Geniculus'' Prescott, 1967 * ''Mesotaenium'' Nägeli, 1849 * ''Netrium'' (Nägeli) Itzigsohn & Rothe, 1856 * '' Nucleotaenium'' Gontcharov & Melkonian, 2010 * '' Planotaenium'' (Ohtani) Petlovany & Palamar-Mordvintseva, 2009 * '' Roya'' West & G.S.West, 1896 * ''Spirotaenia'' Brébisson, 1848 * '' Tortitaenia'' A.J.Brook, 1998 Synonyms: * ''Endospira'' Brébisson, nom. inval., is a synonym of Spirotaenia * ''Entospira'' Kuntze, 1898 is a synonym of ''Spirotaenia'' * ''Polytaenia'' A.J.Brook, 1997, nom. illeg.

Zygnematales
The Zygnematales ( el, ζυγός (''zygós'') and νῆμα (''nḗma'') ( nom.), νήματος (''nḗmatos'') (gen.)), also called the Conjugatales, are an order of green algae, comprising several thousand different species in two families. The larger family Zygnemataceae, with well-known genera such as ''Zygnema'' and ''Spirogyra'', includes members that grow as unbranched filaments, which grow longer through normal cell division. This group includes the desmids. Most members of both families live in freshwater, and form an important component of the algal scum that grows on or near plants, rocks, and various debris. Systematically they fall within the division Charophyta/Streptophyta, in which the land plants (Embryophyta) emerged. Sexual reproduction in Zygnematales takes place through a process called ''conjugation''. Here filaments of opposite gender line up, and tubes form between corresponding cells. The male cells then become amoeboid and crawl across, or sometimes b ...
