The blue-green algae represent a unique stage in the evolution of plant life. The cyanophyta are clearly procaryotic organisms and so they might well be called blue-green bacteria. However they are the only procaryotes able to produce oxygen from water so their photosynthetic activity is like that of the higher plants (Krogmann, 1973).

Nitrogen chlorosis in blue-green algae
Archiv f�r Mikrobiologie, 1969Nitrogen deficient Anacystis nidulans contained normal levels of chlorophyll-a and carotenoids but did not contain any phycocyanin. These organisms also contained large amounts of polysaccharide. The addition of nitrate to a deficient culture resulted in the recovery of normal pigmentation over a period of several hours.
