Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Green Algae
The green algae (: green alga) are a group of chlorophyll-containing autotrophic eukaryotes consisting of the phylum Prasinodermophyta and its unnamed sister group that contains the Chlorophyta and Charophyta/ Streptophyta. The land plants ( Embryophytes) have emerged deep within the charophytes as a sister of the Zygnematophyceae. Since the realization that the Embryophytes emerged within the green algae, some authors are starting to include them. The completed clade that includes both green algae and embryophytes is monophyletic and is referred to as the clade Viridiplantae and as the kingdom Plantae. The green algae include unicellular and colonial flagellates, most with two flagella per cell, as well as various colonial, coccoid (spherical), and filamentous forms, and macroscopic, multicellular seaweeds. There are about 22,000 species of green algae, many of which live most of their lives as single cells, while other species form coenobia (colonies), long filaments ...

Trichosarcina
''Trichosarcina'' is a genus of green algae in the order Ulotrichales. '' Filoprotococcus'' was once regarded as a synonym. However, ''Filoprotococcus'' is now considered valid in its own right. ''Trichosarcina'' is considered to be of uncertain validity. , AlgaeBase accepted only one species, ''Trichosarcina polymorpha''. Its life cycle includes a uniseriate, '' Hormidium''-like phase; a pluriseriate stage, and, finally, a chain of sarcinoid packets which may dissociate. The cells are uninucleate, with a parietal chloroplast and single pyrenoid. Quadriflagellate zoospore A zoospore is a motile asexual spore that uses a flagellum for locomotion in aqueous or moist environments. Also called a swarm spore, these spores are created by some protists, bacteria, and fungi to propagate themselves. Certain zoospores are ...s are produced by cells of the pluriseriate and sarcinoid stages. References Further reading * * *Thompson, Rufus H., and Daniel E. Wujek. "The Identity of ' ...

Ulvophyceae Genera
The Ulvophyceae or ulvophytes are a class of green algae, distinguished mainly on the basis of ultrastructural morphology, life cycle and molecular phylogenetic data. The sea lettuce, ''Ulva'', belongs here. Other well-known members include ''Caulerpa'', ''Codium'', ''Acetabularia'', '' Cladophora'', '' Trentepohlia'' and '' Monostroma''. The Ulvophytes are diverse in their morphology and their habitat. Most are seaweeds such as those listed above. Others, such as '' Rhizoclonium'', '' Pithophora'' and some species of '' Cladophora'' live in fresh water and in some areas are considered weeds. Morphology Ulvophycean algae are diverse in morphology. The thalli are typically colonial (some are unicellular). A few taxa have flagella in their vegetative stage, such as '' Oltmannsiellopsis''. Common forms include filaments (both unbranched and branched), tubular and blade-like thalli (such as in ''Ulva''), and siphonous thalli. Siphonous thalli are composed of a single giant cel ...
