Blue Green Algae, A Superfood for the Brain and More
Hypothesis:Photosynthesis is a process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose....
This was done by separating the photosynthetic pigments (chlorophyll a, chlorophyll b, carotene and xanthophylls) from one another using paper chromatography.

Introduction: "Photosynthesis is the conversion of light energy to chemical energy that is stored in glucose or other organic compounds; it occurs in plants, algae, and certain prokaryotes" (Campbell, G-16).
One very nutritious type of algae is known as “blue-green algae” (Aphanizomenon Flos Aquae, or AFA).
The highest quality blue-green algae come from the Upper Klamath Lake in the Cascade Mountains, Southern Oregon, USA. This ancient lake is fed by seventeen pure mountain streams and geothermal springs, and has the incredible benefit of 30 feet depth of mineral deposits, which results in the most mineral rich alkaline waters on Earth.

As you can see cyanobacteria are a very hot topic concerning both their potential health risks and health assets. This variety of seeing cyanobacteria as both a potential danger and a potential medicine corresponds with the wide variety of blue-green algae that make up the division . When talking about cyanobacteria we are talking about a whole range of species that differ in habitat, organization, health potential, and nutrition, just to name a few. They all have unifying characteristics such as being prokaryotic, having chlorophyll , and the liberation of O2 during photosynthesis, but along with all these similarities they have an equally long list of differences. Some secrete harmful biotoxins and others help to inhibit the growth of retroviruses. When talking about cyanobacteria in general you have to just look at the basic similarities that exist among the species, but at the same time you have to recognize that major differences also exist.
Cyanobacteria are not all bad. They have lots of positive uses in today’s society; as nitrogen fertilizer, for example. Cyanobacteria may also have applications in the area of human health. For example, an extract of (a filamentous blue-green algae) inhibited HIV-1 replication in human T-cell lines (peripheral blood mononuclear cells (PBMC), and Langerhans cells (LC)). A group of scientists at the Dana-Farber Cancer Institute injected these cells with varying concentrations of the extract to observe the effectiveness of different concentrations. What they found was that concentrations between 0.3 and 1.2 mg/ml reduce the viral production by 50% in PBMC cells. This cyanobacteria has antiretroviral activity that could in the future become part of medication for HIV patients (Ayehunie, 1998). Another positive use of cyanobacteria is as a dietary supplement; users say it enhances their mental clarity and energy. Cyanobacteria have many more uses and positive affects ranging from inhibiting the growth of tumors, to lowering cholesterol (Howe, 1997).

Cyanobacteria do not have organs for movement such as flagella, but some filamentous blue-green algae do exhibit a gliding movement. It is thought by some to be a result of slime secretion along with contractile waves on the cells (Bold, 1985).

As I mentioned earlier, unicellular cyanobacteria reproduce asexually by fission. The bacterial chromosome (whose DNA is not associated with the histone protein) is called a genophore. During fission this genophore attaches to the plasma membrane and replicates. Cell division then occurs, separating the bacterium into two identical cells. Because cyanobacteria are prokaryotic they have no nuclei, which means they can not undergo meiosis and fertilization. This limits genetic recombination among cyanobacteria. Yet they do have three ways of genetic exchange. They can exchange genetic material through a conjugation pilus, which physically connects two adjacent cells. Secondly, transformation can occur, which is the absorption of free DNA, which is then expressed in the host. And the third way in which genetic exchange occurs is through transduction, in which a virus enters the blue-green algae cell and uses its DNA to replace the DNA already in the cell. Mutations are also a common occurrence in cyanobacteria cells. All of these factors help cyanobacteria to overcome its genetic recombination limitations due to asexual reproduction (Clark, 1998). The colonial and filamentous cyanobacteria reproduce by fragmentation. In fragmentation segments of the parents break off and float away (they are motile). These fragments then grow into new cells (Bold, 1985).

The intensively cultivated agricultural plants average about 3% in photosynthetic efficiency, and most crops range from 1-4%. This is also typical of algae.

But what about the development of land plants? Why did they stay green? The thoughts are that they had plenty of light and were not pressured to develop more efficient light gathering. That is, the light was not the limiting resource in photosynthesis for plants.
