| Fucus serratus L. |
Fucus serratus is a seaweed of the north Atlantic Ocean, known as toothed wrack or serrated wrack. Carl Linnaeus (Latinized as Carolus Linnaeus, also known after his ennoblement as, May 23 new style (13 May old style 1707 who laid the foundations for Seaweed is a loose colloquial term encompassing macroscopic Multicellular, benthic marine Algae. [1] It is olive–brown in colour and similar to F. vesiculosus and Fucus spiralis. Fucus vesiculosus, known by the common name Bladder wrack, is a Seaweed found on the coasts of the North Sea, the western Baltic Sea Fucus spiralis is a species of seaweed a Brown alga (Heterokontophyta Phaeophyceae) living on the littoral shore of the Atlantic coasts It grows from a discoid holdfast. A holdfast is a Root -like structure that anchors aquatic Sessile organisms such as Seaweed, other sessile Algae, stalked The fronds are flat, about 2 cm wide, bifurcating, and up to 1 m long including a short stipe. A centimetre ( American spelling: centimeter, symbol cm) is a unit of Length in the Metric system, equal to one hundredth The metre or meter is a unit of Length. It is the basic unit of Length in the Metric system and in the International In Botany, a stipe is a supportive structure that may be the stem-like part of the thallus of a Seaweed or a true leaf stem as in Ferns It branches irregularly dichotomously. The flattened blade has a distinct midrib and is readily distinguished from related taxa by the serrated edge of the fronds. A frond is a large Leaf with many divisions to it and the term is typically used for the leaves of palms Ferns or Cycads A frond is It does not have air vesicles, such as are found in F. vesiculosus, nor is it spirally twisted like F. spiralis.
The reproductive bodies form in conceptacles sunken in receptacles towards the tips on the branches. In Phycology, conceptacles are specialised cavities of Seaweeds that contain the reproductive organs Botanical meaning In Botany, the receptacle is the thickened part of a stem from which the Flower organs grow In these conceptacles oogonia and antheridia are produced and after meiosis the oogonia and anteridia are released. An oogonium (plural oogonia) is an Immature ovum. It is a female Gametogonium. An antheridium (plural antheridia) is a Haploid structure or organ producing and containing male Gametes (called antherozoids or Sperm In Biology or life science meiosis (pronounced my-oh-sis is a process of reductional division in which the number of chromosomes per cell is cut in half Fertilisation follows and the zygote develops, settles and grows directly into the diploid sporophyte plant. For other meanings see Zygote (disambiguation. A zygote (from Greek ζυγωτός zugōtos "joined" or "yoked" "Haplo" redirects here For the fictional character see The Death Gate Cycle. All land plants and some Algae, have life cycles in which a haploid Gametophyte generation alternates with a Diploid sporophyte, the generation of a
Distribution and ecology
Fucus serratus is found along the Atlantic coast of Europe from Svalbard to Portugal, in the Canary Islands and on the shores of north-east America. Svalbard is an Archipelago in the Arctic Ocean north of mainland Europe, about midway between Norway and the North Pole. Portugal, officially the Portuguese Republic (República Portuguesa is a country on the Iberian Peninsula. The Canary Islands ( English pronunciation kəˈnæriː ˈaɪləndz Spanish: Islas Canarias, ˈizlas kaˈnarjas are a Spanish The Americas are the lands of the Western hemisphere or New World, consisting of the Continents of North America and South America [2][3] It introduced to Iceland and the Faroes by humans within the last 1000 years where it was first noted in a phycological survey in 1900. Iceland, officially the Republic of Iceland ( ( Ísland or Lýðveldið Ísland ( The Faroe Islands or Faeroe Islands or simply Faroe(s or Faeroes (Føroyar meaning " Sheep Islands" Færøerne Old Norse It grows very well on slow draining shores where it may occupy up to a third of the area of the entire seashore. [4] It often dominates the rocky parts of the lower shore, exposed or emersed in rock pools, on all but the most exposed shores. [5]
Uses
F. serratus is used in Ireland and France for the production of cosmetics and for thalassotherapy. Ireland (pronounced /ˈaɾlənd/ Éire) is the third largest island in Europe, and the twentieth-largest island in the world This article is about the country For a topic outline on this subject see List of basic France topics. Thalassotherapy, (from the Greek word thalassa, meaning " Sea " is the Medical use of Seawater.
