Volvox is a genus of chlorophytes, a type of green algae.

Volvox is the most developed in a series of genera that form spherical colonies.

Each mature Volvox colony is composed of numerous flagellate cells similar to Chlamydomonas, up to 50, 000 in total, and embedded in the surface of a hollow sphere or coenobium containing an extracellular matrix made of a gelatinous glycoprotein.

It has been said that where you find Lemna, you are likely to find Volvox ; and it is true that such water is favorable, but the shading is unfavorable.

Volvox ( technically a coenobium ) is an example of the border between these two states.

Such groups include the Cladocera, planktonic green algae of which Volvox is readily observable, and the protozoa of which tentor can be easily seen without aid.

* Volvocales ( e. g. Volvox, Chlamydomonas )

Volvox developed its colonial lifestyle.

Volvox colony: 1 ) Chlamydomonas-like cell, 2 ) Daughter colony, 3 ) Cytoplasmic bridges, 4 ) Intercellular gel, 5 ) Reproductive cell, 6 ) Somatic cell.

Volvox species can be monoecious or dioecious.

Antonie van Leeuwenhoek first reported observations of Volvox in 1700.

Ancestors of Volvox transitioned from single cells to form multicellular colonies at least, during the Triassic period.

An estimate using DNA sequences from about 45 different species of Volvox and related species suggests that the transition from single cells to undifferentiated multicellular colonies took about 35 million years.

The molecular and genetic basis of asymmetric cell divisions has also been studied in green algae of the genus Volvox, a model system for studying how unicellular organisms can evolve into multicellular organisms.

In Volvox carteri, the 16 cells in the anterior hemisphere of a 32-cell embryo divide asymmetrically, each producing one large and one small daughter cell.

The Volvocaceae are a family of unicellular or colonial biflagellates, including the typical genus Volvox.

Other examples of colonial organisation in protista are Volvocaceae, such as Eudorina and Volvox, the latter of which consists of up to 500 – 50, 000 cells ( depending on the species ), only a fraction of which reproduce.

By the end of 80s, several metal groups formed in Turkey such as Mezarkabul ( Pentagram ), Diken, Volvox and Dr. Skull.

Among notable jazz musicians and bands are vibraphonist Zoran Madžirov, pianists Dragan Soldatovic – Labish and Simon Kiselicki, bands like Sethstat, Letecki Pekinezeri, La Colonie Volvox among others.

Examples include Volvox and its relatives, Scenedesmus, Pediastrum, and Hydrodictyon.

In botany, in addition to a memoir on the minute structure of Volvox ( 1852 ), his work on the structure of fossil plants established British palaeobotany on a scientific basis ; Williamson ranks with Adolphe Theodore Brongniart as one of its founders.

Accordingly the modern study of marine and freshwater algae is called either phycology or algology, depending on whether the Greek or Latin root is used.

However, the Mobile River system has a high incidence of endemism among freshwater mollusks and biodiversity is high.

Farther north the western depression, known as the Albertine Rift is occupied for more than half its length by water, forming the Great Lakes of Tanganyika, Kivu, Lake Edward and Lake Albert, the first-named over 400 miles ( 600 km ) long and the longest freshwater lake in the world.

* Champ is the name given to a reputed lake monster living in Lake Champlain, a natural freshwater lake in North America, partially situated across the U. S .- Canada border in the Canadian province of Quebec and partially situated across the Vermont-New York border.

The Baltic Sea's salinity is much lower than that of ocean water ( which averages 35 ‰), as a result of abundant freshwater runoff from the surrounding land, combined with the shallowness of the sea itself ; indeed, runoff contributes roughly one-fortieth its total volume per year, as the volume of the basin is about 21, 000 km³ and yearly runoff is about 500 km³.

At the semi-enclosed bays with major freshwater inflows, such as head of Finnish Gulf with Neva mouth and head of Bothnian gulf with close mouths of Lule, Tornio and Kemi, the salinity is considerably lower.

The zebrafish, Danio rerio, is a tropical freshwater fish belonging to the minnow family ( Cyprinidae ) of order Cypriniformes.

Of the three ecoregions it is the richest in terms of freshwater species diversity.

The ring-shaped atoll completely encloses a stagnant freshwater lagoon, and is.

The fossils of Mesosaurus, a freshwater reptile rather like a small crocodile, found both in Brazil and South Africa, are one example ; another is the discovery of fossils of the land reptile Lystrosaurus from rocks of the same age from locations in South America, Africa, and Antarctica.

The first such prehistoric lake is named " Lake Amora ", which was a freshwater or brackish lake that extended at least south of the current southern end of the Dead Sea and north, well above the present Hula Depression.

This is believed to be the cause of the recent appearance of large sinkholes along the western shore — incoming freshwater dissolves salt layers, rapidly creating subsurface cavities that subsequently collapse to form these sinkholes.

When a Ghyben-Herzberg lens is fully formed, its floating nature will push a freshwater head above mean sea level, and if the island is wide enough, the depth of the lens below mean sea level will be 40 times the height of the water table above sea level.

' Waterzooi ' is a local stew originally made from freshwater fish caught in the rivers and creeks of Ghent, but nowadays often made with chicken instead of fish.

Trout is the most common freshwater fish on the German menu ; pike, carp, and European perch also are listed frequently.
