Ectocarpales
Ectocarpales is a very large order in the brown algae (class Phaeophyceae). The order includes families with pseudoparenchymatous ( Splachnidiaceae) or true parenchymatous ( Scytosiphonaceae) tissue. Pseudoparenchymatous refers to a filamentous alga with cells packed very close together to give an appearance of parenchymatous tissue, the latter being composed of cells which can truly divide in three dimensions, unusual among the algae. Filamentous algae are composed of cells that divide along a single plane, allowing only elongation to form filaments of one or more rows of cells. Algae that can divide in two planes can form sheet-like thalli or bodies. Cells that can divide in a third plane potentially allow for the organism to develop a more complex body plan, and diversification of body plans into an erect thallus of some sort and a holdfast for attaching the upright portion to the substrate. A 2014 classification recognizes the following families: *Acinetosporaceae H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brown Algae
Brown algae (singular: alga), comprising the class Phaeophyceae, are a large group of multicellular algae, including many seaweeds located in colder waters within the Northern Hemisphere. Brown algae are the major seaweeds of the temperate and polar regions. They are dominant on rocky shores throughout cooler areas of the world. Most brown algae live in marine environments, where they play an important role both as food and as a potential habitat. For instance, '' Macrocystis'', a kelp of the order Laminariales, may reach in length and forms prominent underwater kelp forests. Kelp forests like these contain a high level of biodiversity. Another example is '' Sargassum'', which creates unique floating mats of seaweed in the tropical waters of the Sargasso Sea that serve as the habitats for many species. Many brown algae, such as members of the order Fucales, commonly grow along rocky seashores. Some members of the class, such as kelps, are used by humans as food. Between 1,5 ...

Leathesia Difformis
''Leathesia difformis'', is a synonym for ''Leathesia marina'' (Lyngbye) Decaisne, 1842, commonly known as the sea cauliflower and the sea potato. It is a species of littoral brown algae in the class Phaeophyceae and the order Ectocarpales which is commonly attached to other seaweeds and sometimes rocks. When young, the organism is solid but as it matures it becomes hollow and somewhat convoluted and has the appearance of a small leathery brown bag about the same size as a tennis ball. The texture is rubbery and the outer surface smooth. These brain-like brown seaweeds can be found growing on rock or as epiphytes on other seaweeds in the mid to low intertidal. Individuals can grow to ~ in diameter. Young individuals can resemble other globular forms of algae, such as '' Soranthera ulvoidea''. To determine if it is '' Leathesia'', squeeze and flatten a piece between your fingers. Leathesia will break apart into filaments whereas other globular forms will flatten but remain ...

Chordariaceae
Chordariaceae is a family of brown algae. Members of this family are may be filamentous, crustose with fused cells at the base, or they may be terete and differentiated into a central medulla and an outer photosynthetic cortex. They have a sporphytic thallus usually aggregated to form a pseudo- parenchyma.Pound, F. E. 1962 ''The Biology of the Algae'' Edward Arnold Ltd.

Cambridge
Cambridge ( ) is a university city and the county town in Cambridgeshire, England. It is located on the River Cam approximately north of London. As of the 2021 United Kingdom census, the population of Cambridge was 145,700. Cambridge became an important trading centre during the Roman and Viking ages, and there is archaeological evidence of settlement in the area as early as the Bronze Age. The first town charters were granted in the 12th century, although modern city status was not officially conferred until 1951. The city is most famous as the home of the University of Cambridge, which was founded in 1209 and consistently ranks among the best universities in the world. The buildings of the university include King's College Chapel, Cavendish Laboratory, and the Cambridge University Library, one of the largest legal deposit libraries in the world. The city's skyline is dominated by several college buildings, along with the spire of the Our Lady and the English Marty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Robert Kaye Greville
Dr. Robert Kaye Greville FRSE FLS LLD (13 December 1794 – 4 June 1866) was an English mycologist, bryologist, and botanist. He was an accomplished artist and illustrator of natural history. In addition to art and science he was interested in causes like abolitionism, capital punishment, keeping Sunday special and the temperance movement. He has a mountain in Queensland named after him.
