Rhodogorgonales
The Rhodogorgonales are an order of red algae, a sister group to the corallines. They are always thalloid and calcified; their calcification is very different from the corallines, as individual calcite crystals are deposited in the cell wall of specialised cells; this suggests that the evolution of calcification may have been independent from the corallines. They have no fossil record. Unlike the corallinales and sporolithales, their closest relatives, these thalli are loose aggregations of hair-like cells, with the middle portion formed of rhizoid-like filaments. Spores are borne on the end of hair-like cells (cortical fascicles).

Florideophyceae
Florideophyceae is a class of red algae. They were once thought to be the only algae to bear pit connections, but these have since been found in the filamentous stage of the Bangiaceae. They were also thought only to exhibit apical growth, but there are genera known to grow by intercalary growth. Most, but not all, genera have three phases to the life cycle. Classification There are various classification schemes; see red algae. One option is to use the following: Subclass Hildenbrandiophycidae * Hildenbrandiales Subclass Nemaliophycidae * Acrochaetiales * Balbianiales * Balliales * Batrachospermales * Colaconematales * Nemaliales * Palmariales * Entwisleiales * Thoreales Subclass Corallinophycidae * Corallinales * Corallinapetrales * Rhodogorgonales * Sporolithales The subclass Corallinophycidae was introduced in 2007. Subclass Ahnfeltiophycidae * Ahnfeltiales * Pihiellales Subclass Rhodymeniophycidae * Bonnemaisoniales * Ceramiales * Gelidiales * Gigarti ...

Red Algae
Red algae, or Rhodophyta (, ; ), are one of the oldest groups of eukaryotic algae. The Rhodophyta also comprises one of the largest phyla of algae, containing over 7,000 currently recognized species with taxonomic revisions ongoing. The majority of species (6,793) are found in the Florideophyceae (Class (biology), class), and mostly consist of multicellular, ocean, marine algae, including many notable seaweed, seaweeds. Red algae are abundant in marine habitats but relatively rare in freshwaters. Approximately 5% of red algae species occur in freshwater environments, with greater concentrations found in warmer areas. Except for two coastal cave dwelling species in the asexual class Cyanidiophyceae, there are no terrestrial species, which may be due to an evolutionary bottleneck in which the last common ancestor lost about 25% of its core genes and much of its evolutionary plasticity. The red algae form a distinct group characterized by having eukaryotic cells without flagella and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Algae Orders
Red is the color at the long wavelength end of the visible spectrum of light, next to orange and opposite violet. It has a dominant wavelength of approximately 625–740 nanometres. It is a primary color in the RGB color model and a secondary color (made from magenta and yellow) in the CMYK color model, and is the complementary color of cyan. Reds range from the brilliant yellow-tinged scarlet and vermillion to bluish-red crimson, and vary in shade from the pale red pink to the dark red burgundy. Red pigment made from ochre was one of the first colors used in prehistoric art. The Ancient Egyptians and Mayans colored their faces red in ceremonies; Roman generals had their bodies colored red to celebrate victories. It was also an important color in China, where it was used to color early pottery and later the gates and walls of palaces. In the Renaissance, the brilliant red costumes for the nobility and wealthy were dyed with kermes and cochineal. The 19th century brought the ...

Marinella
Marinella ( el, Μαρινέλλα) (born 20 May 1938, Thessaloniki) is one of the most popular Greek singers whose career has spanned several decades. She has sung professionally since 1957. Since the beginning of her career, she has released 66 solo albums and has been featured on albums by other musicians. She still sings today and stands out for the range of her voiceDragoumanos, Petros (2009). ''Elliniki Diskografia 1950–2009'' (''Greek Discography 1950–2009'') Early life She was born Kyriaki Papadopoulou (Κυριακή Παπαδοπούλου), in the city of Thessaloniki in northern Greece. Her parents were Greek refugees from Constantinople. She is the fourth and last child of a large family, which despite its poverty, was rich in love and in artistic vein. The whole family gathered around the turntable and sang, while her father tried to teach children the steps of the waltz and the tango. From the age of four years singing on the radio broadcast in "Pediki Ora ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ernst Haeckel
Ernst Heinrich Philipp August Haeckel (; 16 February 1834 – 9 August 1919) was a German zoologist, naturalist, eugenicist, philosopher, physician, professor, marine biologist and artist. He discovered, described and named thousands of new species, mapped a genealogical tree relating all life forms and coined many terms in biology, including ''ecology'', ''phylum'', ''phylogeny'', and '' Protista.'' Haeckel promoted and popularised Charles Darwin's work in Germany and developed the influential but no longer widely held recapitulation theory ("ontogeny recapitulates phylogeny") claiming that an individual organism's biological development, or ontogeny, parallels and summarises its species' evolutionary development, or phylogeny. The published artwork of Haeckel includes over 100 detailed, multi-colour illustrations of animals and sea creatures, collected in his '' Kunstformen der Natur'' ("Art Forms of Nature"), a book which would go on to influence the Art Nouveau artistic ...
