IN this article we will discuss about the Subject-Matter and Mechanism of Nitrogen Fixing Systems. Subject-Matter of Nitrogen Fixing Systems: Blue-green algae share with bacteria the potentiality of fixing atmospheric nitrogen. To date, nearly 50 spp. are reported to be active nitrogen fixers. Nitrogen fixation was demonstrated initially in Nostocpunctiformae and Anabaena sp. In 1968, […]

In this article we will discuss about the primary and secondary reactions of photosynthesis. Ruben and his co-workers in early 1943 used 18O and proved that oxygen evolved in photosynthesis came from water. Photosynthesis allowed to proceed in H2O18 and normal CO2, had molecular oxygen evolved with heavy isotopes. When photosynthesis was carried out in […]
Commonly Used Methods of Measuring Photosynthesis

Several experiments can be performed to demonstrate the process of photosynthesis. Usually, the process is demonstrated by the liberation of O2 which is a by-product from a green illuminated water plant. A bunch of Hydrilla plants cut under water are placed under a glass funnel dipping in water with their cut ends directed towards the […]
