However, a few species of blue-green algae, such as Microcystis, Aphanizomenon, and Anabaena, produce toxins capable of causing illness in humans and toxins can cause gastroenteritis, neurological disorders, and possibly cancer. In this case, illness is caused by the ingestion of the toxin produced by the organisms, rather than ingestion of the organism . summary Blue-green algae (also known as cyanobacteria) and the toxins they can produce pose serious economic, environmental, and public health problems by: 1.

Algae and cyanobacteria in fresh water T he term algae refers to microscopically small, unicellular organisms, some of which form colonies and thus reach sizes visible to the naked eye as minute green particles. These organisms are usually finely dispersed throughout the water and may cause considerable turbidity if they attain high densities. Cyanobacteria / s aɪ ˌ æ n oʊ b æ k ˈ t ɪər i ə /, an aa kent as Cyanophyta, is a phylum o bacteria that obtain thair energy throu photosynthesis. The name "cyanobacteria" comes frae the colour o the bacteria (Greek: κυανός (kyanós) = blue).Altho eften cried blue-green algae, that name is a misnomer as cyanobacteria are prokaryotic an algae are eukaryotic.(unranked): Terrabacteria.

The major groups are green algae, yellow algae, brown algae, red algae, dinoflagellates, and sometimes blue-green algae (cyanobacteria). Algae are usually classified according to color. The following examples are given in the text; others are also acceptable: *green algae-chlorella, Chlamydomonas, Protococcus, desmids, volvox, Ulothrix, spirogyra. Blue Green Algae Season Summary. The season summary status of Blue-green Algae shown on the map reflects conditions from early June thru mid October. Observations and samples were collected once each week.

Get this from a library. Summary of the classification of blue-green algae. [Francis Drouet]. Different classification systems answer this question in different ways, with some even splitting the group between the kingdoms Protista and Plantae.

Here we have grouped algae with protozoa and slime molds in Protista because mthe majority of algae are unicellular, and even the multicellular algae are structurally simple compared to true plants.

Algae - Algae - Classification of algae: The classification of algae into taxonomic groups is based upon the same rules that are used for the classification of land plants, but the organization of groups of algae above the order level has changed substantially since Early morphological research using electron microscopes demonstrated differences in features, such as the.

Cyanobacteria / s aɪ ˌ æ n oʊ b æ k ˈ t ɪər i ə /, also known as Cyanophyta, are a phylum consisting of free-living photosynthetic bacteria and the endosymbiotic plastids, a sister group to Gloeomargarita, that are present in some commonly obtain their energy through oxygenic photosynthesis.

Algae are chlorophyll-bearing simple, thalloid, autotrophic and largely aquatic organisms. Depending on the type of pigment possesed and the type of stored food, algae are classfied into three classes, namely Chlorophyceae, Phaeophyceae and Rhodophyceae.

Algae (/ ˈ æ l dʒ i, ˈ æ l ɡ i /; singular alga / ˈ æ l ɡ ə /) is an informal term for a large, diverse group of photosynthetic eukaryotic organisms that are not necessarily closely related, and is thus ed organisms range from unicellular microalgae, such as Chlorella and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow.

Cyanobacteria are a taxon of bacteria which conduct are not algae, though they were once called blue-green is a phylum of bacteria, with about endosymbiont theory, chloroplasts (plastids) are descended from cyanobacteria. Their DNA profile is evidence for this.

Cyanobacteria have an extremely long fossil record, starting at least Domain: Bacteria. Cellular structure. Green algae have chloroplasts that contain chlorophyll a and b, giving them a bright green color, as well as the accessory pigments beta carotene (red-orange) and xanthophylls (yellow) in stacked thylakoids.

The cell walls of green algae usually contain cellulose, and they store carbohydrate in the form of starch. All green algae have mitochondria with flat (unranked): Archaeplastida. •The current systems of classification of algae are based on the following main criteria: o kinds of photosynthetic pigments, o type or chemical nature of photosynthetic energy storage products o photosynthetic membranes’ (thylakoids) organization and other features of the chloroplasts.

o cell wall composition and structure. o the presence or absence of flagella (as well as the number and. Blue-green algae, also called cyanobacteria, any of a large, heterogeneous group of prokaryotic, principally photosynthetic organisms. Cyanobacteria resemble the eukaryotic algae in many ways, including morphological characteristics and ecological niches, and were at one time treated as algae, hence the common name of blue-green algae.

Other researchers, such as E. G. Pringsheim writing insuspected separate origins for bacteria and blue-green algae. Inthe influential Bergey's Manual published a new edition coining the term cyanobacteria to refer to what had been called blue-green algae, marking the acceptance of this group within the Monera.

Summary.For example, some algae carry out photosynthesis, and also take up dissolved organic matter by osmosis to derive energy, while a few species rely completely on external energy sources.

There are several types of algae such as blue-green algae, red algae, green algae, and brown algae. They are now considered as more related to bacteria than algae.THE TAXONOMY OF BLUE-GREEN ALGAE By B.

A. WHITTON Department of Botany, University of Durham The conventions at present used in the classification of blue-green algae frequently prove unsatisfactory.

A solution is suggested which requires the simultaneous use of two different approaches.
