- Bacteria are examples of the prokaryotic cell type. An example is E. coli. In general, prokaryotic cells are those that do not have a membrane-bound nucleus. In fact pro-karyotic is Greek for before nucleus. Besides bacteria, the cyanobacteria (blue-green algae) are a major group of prokaryotes.

- Formerly called blue-green algae and often called pond scum, cyanobacteria are one of the best prokaryotic phyla in which to study bioenergetics and stress biology, because of their cosmopolitan occurrence, archaic origin, and relatively simple bacterial architecture with a physiology ancestral to higher plants.

Is the Red Sea red? The relative abundance of phycobilin pigments, the reddish phycoerythrin and the blue phycocyanin, explain the color of cyanobacteria. Microscopically, the blue phycocyanin pigment, the green chlorophyll, and the accessory pigments give rise to blue-green algae.

Stromatolites - The longest living organisms on the Earth Nonmairine stromatolites have been found in streams, lakes, thermal springs, and even frozen lakes (McNamara and Awaramik, 1992). Cyanobacteria is key organism in the formation of microbial carbonates (Riding, 2000). Bacteria are prokaryotes; they lack a nucleus and other membrane bound cell organelles.

prokaryote prokaryote. a unicellular organism lacking a true nucleus and nuclear membrane, having genetic material composed of a single molecule of double-stranded DNA. Prokaryotes with the exception of mycoplasmas have a rigid cell wall. Includes the blue-green algae and bacteria—the Cyanophyceae. unicellular organism that does not contain a true nucleus surrounded by a double membrane; a bacterium. Division usually occurs through simple fission. Also spelled procaryote. Compare eukaryote-prokaryotic adj.

- Architects of earth's atmosphere. Cyanobacteria are aquatic and photosynthetic, that is, they live in the water, and can manufacture their own food. Because they are bacteria, they are quite small and usually unicellular, though they often grow in colonies large enough to see.

Algae description and types The exact nature of the chloroplasts is different among the different lines of algae. Cyanobacteria are organisms traditionally included among the algae, but they have a prokaryotic cell structure typical of bacteria and conduct photosynthesis directly within the cytoplasm, rather than in specialized organelles.

Cyanobacteria The name cyanobacteria comes from the color of the bacteria (Greek: κυανός (kyanos) = kyanós). Blue they are often called-blue green (algae but some consider that name a, misnomer as cyanobacteria are prokaryotic and algae should be, eukaryotic although other definitions of algae encompass prokaryotic). organismsany cyanobacteria are able to reduce nitrogen and carbon dioxide under aerobic conditions, a fact that may be responsible for their evolutionary and ecological success. The water-oxidizing photosynthesis is accomplished by coupling the activity of photosystem (PS) II and I (Z-scheme).

Prokaryote 3D animation of a prokaryotic cell that shows all the elements that compose it. A prokaryote is a single-celled organism that lacks a membrane-bound nucleus (karyon), mitochondria, or any other membrane-bound organelle. The word prokaryote comes from the Greek πρό- (pro -) before and καρυόν (karyon)  nut or kernel .nother difference is that ribosomes in prokaryotes are smaller than in eukaryotes. However, two organelles found in many eukaryotic cells, mitochondria and chloroplasts, contain ribosomes similar in size and makeup to those found in prokaryotes.

- Answers. Best Answer: Eubacteria, also know as “true bacteria”, are microscopic prokaryotic cells. Cyanobacteria, also called blue-green algae, are Eubacteria that have been living on our planet for over 3 billion years. Blue-green algae grow in the shallow parts of the ocean.-all eubacteria are unicellular --microscopic --some can make their own food (autotrophs) while others rely on external sources of nutrition (heterotrophs http://facstaff.uww.edu/wentzl/eubacteri...

Cyanobacteria Cyanobacteria use the energy of sunlight to drive photosynthesis, a process where the energy of light is used to split water molecules into oxygen, protons, and electrons.

Monera In addition to the heterotrophs, there are many kinds of autotrophic bacteria, able to produce their own food. These autotrophs may be photosynthetic or chemosynthetic and may or may not use oxygen in their synthetic pathways. Cyanobacteria are the largest group of photosynthetic eubacteria. The cells of these bacteria are often much larger than other bacteria, which in the past led this group to be classified as algae rather than bacteria. In fact, cyanobacteria are still sometimes referred to as blue-green algae.

- Cyanobacteria are Gram negative bacteria, meaning that they do not stain purple with Gram's stain. The Gram stain dyes peptidoglycan purple. Peptidoglycan is the polymer that makes up the tough cell-wall layer in the cell envelopes of most bacteria.

Algae & Cyanobacteria Cyanobacteria are sometimes considered algae, but they are actually bacteria (prokaryotic), where the term algae is now reserved for eukaryotic organisms. They also derive their energy through photosynthesis, but lack a nucleus or membrane bound organelles, like chloroplasts.ctually, cyanobacteria may have evolved into the first chloroplasts, as evidenced by similar structural and genetic traits. Cyanobacteria have a unique set of pigments used in photosynthesis, called the phycobiliproteins (phycobilins), which can give some of them a blue-green color.

Brief Notes on Prokaryotic and Eukaryotic Algae The blue-green algae (Cyanophyceae or Cyanophycophyta) are prokaryotic algae. In these algae, their nuclear materials, deoxyribo-nucleic acid (DNA), is not delimited from the remainder of the protoplasm by a nuclear membrane, but rather it is dispersed to some degree throughout the cell. The membrane-bounded plastids are absent; the photosynthetic lamellae occur freely in the cytoplasm.

Learn About Prokaryotic Cells Prokaryotic Cells. Prokaryotes are single-celled organisms that are the earliest and most primitive forms of life on earth. As organized in the Three Domain System, prokaryotes include bacteria and archaeans. Some prokaryotes, such as cyanobacteria, are photosynthetic organisms and are capable of photosynthesis.

- The theory postulates that the mitochondria evolved from aerobic bacteria (probably proteobacteria, related to the rickettsias), and that the chloroplast evolved from endosymbiotic cyanobacteria (autotrophic prokaryotes).The evidence for this theory is compelling as a whole, and it is now generally accepted.he theory postulates that the mitochondria evolved from aerobic bacteria (probably proteobacteria, related to the rickettsias), and that the chloroplast evolved from endosymbiotic cyanobacteria (autotrophic prokaryotes).

- Blue-green algae make up the division Cyanophyta in the kingdom Monera, which is made up of about 1,500 species of prokaryotic organisms. There is disagreement on whether or not this division should be considered algae or bacteria. Cyanobacteria (Blue Green Algae) differ from other types of bacteria in that they have chlorophyll a, which other photosynthetic bacteria don’t have. Another characteristic that supports the algae argument is the fact that free oxygen is given off in blue-green algae photosynthesis but it is not given off in the photosynthesis of other bacteria. Many bacteria split H 2 S instead of H 2 O as a source of electrons during their photosynthesis; this is why they don’t produce free O 2.
