Question

Why are blue green algae included under monera and not under plantae? Discuss the importance of the cyanobacteria.

Answer 1

First organisms to possess two photosystems and to supply organic material and provide oxygen as a bi-product as photosynthetic activity. The unicellular cyanobacterium Synechocystis sp. It continues to be a crucial model organism.

Complete answer:
-IMPORTANCE
-Many – fix or convert atmospheric nitrogen into usable forms through organic processes when other forms are unavailable because atmospheric nitrogen is unavailable to most living organisms. eg., Nostoc.
-Oscillatoria and few other cyanobacteria are often used as pollution indicators.
-"Super Blue green algae" are basically expensive green algae during which cyanobacterium may be a single celled organism which produces its own food through photosynthesis.
-Symbiotic relationships they need symbiotic relationships with protozoa, fungi, and nitrogen fixing species form associations with angiosperms. they're photosynthetic partners in most lichen associations. Eg., Anabaena azollae colonizes the floating aquatic fern
-Apart from this, cyanobacteria also colonizes the roots of upper plants. The coralloid roots of Cycas are good samples of this association.
-Its used as food: Spirulina are sold within the market thanks to their nutritive value. Spirulina tablets are sold everywhere the planet as “health food”
-ITS APPLICATIONS IN BIOTECHNOLOGY
-Cyanobacteria are cultured in specific media. Cyanobacteria are often helpful in agriculture as they need the potential to repair atmospheric nitrogen to soil.
-HEALTH BENEFITS
-Cyanovin, a secondary metabolite which has been shown to possess anti-HIV activity.
-Consumption of edible blue chlorophyte can also reduce risks of cataracts and age related degeneration
-Sulfate which is a polysaccharides exhibit antitumor, anticoagulant, anti-mutagenic, antiinflammatory, antimicrobial, and even antiviral activity against HIV, herpes, and hepatitis.

Note: -RECENT RESEARCHES
-Currently efforts are underway to commercialize algae-based fuels like diesel, gasoline and jet fuel.
-Researchers from a corporation called Algenol have cultured genetically modified cyanobacteria in sea water inside a transparent plastic enclosure due that they first make sugar (pyruvate) from $CO_2$ and therefore the water via photosynthesis.
