China, with one-fifth of the world's population, accounts for two-thirds of the world's reported aquaculture production.. Aquaculture is the farming of fish and other aquatic life in enclosures, such as ponds, lakes and tanks, or cages in rivers and coastal waters. NCERT Solutions Class 11 Biology Biology Sample Papers. Porphyra species are the largest source of food from red seaweeds. Released monospores lack a cell wall. The neurologic features do not distinguish among the HPs, but skin lesions are present in VP and HC and absent in AIP. Porphyra can bear desiccation, so can live in the highest, driest reaches of the intertidal zone. 1996 Mar. What are red algae? J Nutr Sci Vitaminol (Tokyo). Porphyra thalli appear in nature as free-living organisms, and their microscopic filaments bore into calcium carbonate substrates such as oyster shells. Diatoms constitute a major part of algae, and most of them are unicellular organisms. Sexual reproduction is oogamous and accompanied by complex post fertilisation developments. Specific general characteristics of algae are common to plants as well as animals. Distinctive characteristics: Collection notes: Be sure to rise off critters living in this seaweed. At least two types of phycoerythrin (I and II) can be distinguished by electrophoresis, chromatography, and spectral characteristics. More specifically, it belongs to red algae phylum of laver species, comprising approximately 70 species. We describe the genomes of three bacteria in the phylum Planctomycetes (designated P1, P2 and P3) that were isolated from blades of Porphyra umbilicalis (P.um.1).

Farming of these valuable marine crops was revolutionized by the discovery of their life cycle in the 40’s. One of the MAAs, Porphyra-334 was subjected to study its opto electrical properties by Silicon nano-ribbon field effect transistor (FET) device and by cyclic voltammetry. Description of Rhodophyceae (Red Algae): It is a large group of algae consisting of about 831 genera and over 5;250 species. Edibility: Delicious! Only a few are found in freshwater. This bright ocean layer is called the sunlit zone or the euphotic zone (euphotic means "well lit" in Greek) or the epipelagic zone (epipelagic means "upon the sea"). Appearance Porphyra thalli appear in nature as free-living, easily visible thin blades (the phase that is harvested for nori) and as tiny, microscopic filaments that bore into calcium carbonate substrate. These species bear some peculiar characteristics common to all three, viz., presence of microscopic denticulate marginal growths, monoecious, and for having monostromatic type of thallus. Cytoskeletal motor proteins in Porphyra are restricted to a small set of kinesins that appear to be the only universal cytoskeletal motors within the red algae. Characteristics of Rhodophyceae 3. At least two types of phycoerythrin (I and II) can be distinguished by electrophoresis, chromatography, and spectral characteristics. Characteristics of Algae.

Name three kinds of fungi-like protists… Traditionally, Porphyra species have been largely delineated on the basis of blade characteristics Porphyra-334, a type of mycosporine-like amino acids (MAAs), also plays an important role in photoprotection for a variety of marine organisms including bacteria and algae. Samples of P. suborbiculata (Kjellm. 37(3):230-5. Hence, one site at Horse Shoe Beach, Cove Island Park, Stamford, CT was chosen to be monitored from January 1999 to May 2002. Ecklonia Maxima, Laminaria Pallida, Ulva and Porphyra are our species. Both flanking (EPIC) and internal ‘intron-specific’ PCR primers were developed and used to screen for the 1506 SSU nuclear ribosomal hemiphylla in unisexual culture (FV) and in mixed culture with male vegetative tissues (FV-M) were followed at 5–20 °C, 10 and 80 μmol photons m−2 s−1. SARGASSUM 3. In Tyler-Walters H. and Hiscock K. (eds) Marine Life Information Network: Biology and Sensitivity Key Information Reviews , [on-line]. Porphyria is a blond with long, beautiful hair. Increased dictyosome activity resulting in the production of small and large fibrous vesicles is a characteristic feature of the developing monospores. A compilation of seaweeds gathered from the surf and beach deposits of Maine, Massachusetts, New Hampshire and Canada. Biochar is found to have advantageous characteristics, such as a unique pore structure, large specific surface area, complex surface-active functional groups, and stable chemical properties . Description of Rhodophyceae 2. Porphyria Causes No matter what kind of porphyria you have, it has the same root cause: a problem with how your body makes a substance called heme. The body surface is perforated by numerous pores, the Ostia through which water enters the body and one or more large openings, the oscula by which the water exists. The design of the dikes depends primarily on soil characteristics. [Middle English porosite, from Old French, from Medieval Latin porōsitās, from porōsus, porous; see porous.] Although MAA and DNA molecules have been intensively studied, … Atlantic Porphyra (Klein et al., 2003) by surveying a large collection of Porphyra for the presence of group-I introns in the SSU and characterizing their size, structure, and utility for phylogeo-graphic studies.
