Nephrophyceae
Nephroselmidaceae is a family of green algae, the only family in the order Nephroselmidales and the class Nephrophyceae within the division Chlorophyta Chlorophyta or Prasinophyta is a taxon of green algae informally called chlorophytes. The name is used in two very different senses, so care is needed to determine the use by a particular author. In older classification systems, it refers to a ....

Nephroselmis
''Nephroselmis'' is a genus of green algae. It has been placed in the family Nephroselmidaceae, although a 2009 study suggests that it should be separated into its own class, Nephroselmidophyceae. One species can be an endosymbiont of ''Hatena arenicola''. Morphology The cell body is right-left flattened. On the ventral side are two heterodynamic unequal flagella, the shorter beats towards the anterior direction while the long trails behind. ''Nephroselmis'' have a single cup-shaped chloroplast that contains an eyespot in its anterior-ventral edge below the short flagellum and a pyrenoid with starch plates. Vacuole is located in the left-anterior side, nucleus is located in the right-posterior side. The flagellar root system consists of a rhizoplast and three microtubular roots, one of which is multilayered. All the cells surface area is covered with layers of unminerallized scales, while the surface of the flagella has hairs as well. The cell body surface is covered by two to ...

Chlorophyta
Chlorophyta or Prasinophyta is a taxon of green algae informally called chlorophytes. The name is used in two very different senses, so care is needed to determine the use by a particular author. In older classification systems, it refers to a highly paraphyletic group of ''all'' the green algae within the green plants (Viridiplantae) and thus includes about 7,000 species of mostly aquatic photosynthetic eukaryotic organisms. In newer classifications, it refers to the sister clade of the streptophytes/ charophytes. The clade Streptophyta consists of the Charophyta in which the Embryophyta (land plants) emerged. In this latter sense the Chlorophyta includes only about 4,300 species. About 90% of all known species live in freshwater. Like the land plants (embryophytes: bryophytes and tracheophytes), green algae (chlorophytes and charophytes besides embryophytes) contain chlorophyll a and chlorophyll b and store food as starch in their plastids. With the exception of Palmop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paul Silva
Paul Claude Silva (October 31, 1922 – June 12, 2014) was a phycologist, marine biologist, and algal taxonomist considered to be the world's leading expert in the chlorophyte green algal genus ''Codium''. Silva was also an expert in botanical nomenclature and was an editor of the International Code of Botanical Nomenclature's Eighth through Sixteenth International Botanical Congresses. Biography Silva completed his undergraduate degree at the University of Southern California, though his education was interrupted by World War II. He served in the US Navy on the USS Darby, participating in the Battle of Leyte Gulf. He attended Stanford University for his master's degree studying under Gilbert Morgan Smith, and University of California, Berkeley for his Ph.D. Silva later worked as a Research Botanist and Curator of Algae at the UCB herbarium. Honours He has been honoured in the naming of several taxa of algae. In 1999, ''Silvetia'' In the Fucaceae family) was published by bota ...
