Between 28 and 184 independent HGT events (each represented by a single HGT gene or a family of HGT paralogs) were found in the 23 species with 1.08 to 3.79 genes per family (data file S1). ent groups of photosynthetic eukaryotes hints at a broader principle for prokaryotic HGT in phytoplankton genomes. In this article the algae are defined as eukaryotic (nucleus-bearing) organisms that photosynthesize but lack the specialized multicellular reproductive structures of plants, which always contain fertile gamete-producing cells surrounded by sterile cells.Algae also lack true roots, stems, and leavesfeatures they share with the avascular lower plants (e.g., mosses, liverworts, and hornworts). Global change will affect multiple physico-chemical parameters of the oceans, amongst them also the abundances of macronutrients like phosphorus and nitrogen that are critical for phytoplankton growth. The term "algae also known as blue-green algae as well as eukaryotic organisms (all other algal species). auto-mixo or heterotroph). Read more Phytoplankton: Definition, Example Dissolved CO 2 in the oceans is highly variable on regional and seasonal scales (Takahashi et al., 2014) and can be particularly high in coastal upwelling regions (Feely et al., 2008) where eukaryotic phytoplankton are abundant, making it likely that coastal eukaryotic phytoplankton regularly experience large fluctuations in CO 2. Lake Erie is an ideal location, because it experiences an annual shift in the phytoplankton community from eukaryotic phytoplankton in the early summer to cyanobacteria in the late summer/early fall (Bridgeman et al., 2012). The majority (Cryptophytes, which contain phycoerythrin in addition to chl a, are a nota- Definition. Most people chose this as the best definition of eukaryotic: (biology) Having complex See the dictionary meaning, pronunciation, and sentence examples. Micrometazoa <200 um and also larger metazoans are thus excluded from this definition. Definition. Dinoflagellates are single-celled algae residing in marine and freshwater aquatic habitat. . A protist is a eukaryotic organism that is not an animal, plant, or fungi. Phytoplankton Definition Phytoplankton are a type of microscopic plankton capable of photosynthesis found in oceans, seas, and freshwater, and an essential component of aquatic ecosystems.. Phytoplankton (from Greek phyton, or plant), autotrophic, prokaryotic or eukaryotic algae that live near the water surface where there is sufficient light to support photosynthesis. Dictionary ! Phytoplankton Definition Phytoplankton are a type of microscopic plankton capable of photosynthesis found in oceans, seas, and freshwater, and an essential component of aquatic ecosystems. Recent progress in algal genetic resources and environmental chemistry have promoted a renewal of interest in the role of vitamins in governing phytoplankton dynamics, and illuminated amazing versatility in phytoplankton vitamin metabolism. Marine phytoplankton organisms account for more than 45% of the photosynthetic net primary production on Earth. Specific organisms currently being analyzed in addition to the marine cyanobacteria include the eukaryotic phytoplankton Emiliania huxleyi and Phaeocystis sp. The largest families 05 0 100 150 200 250 300 Examples of prokaryotes are blue-green algae, bacteria and mycoplasma. To get really specific on the true phytoplankton definition, theyre neither clearly plants nor animals. There are two primary types of cells: eukaryotic cells and prokaryotic cells. sequestration, nutrient recycling), sustaining the life of all other aquatic organisms.
