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, Fay made the suggestion that [...]
The upcoming discussion will update you about the difference between Photorespiration and True Respiration. 1. Effect of O2 Concentration: The most obvious difference between true respiration and photorespiration is the effect of oxygen concentration on the rate of two processes. In most tissues true respiration is saturated at oxygen concentration of 2-3% and and beyond this percentage virtually no increase [...]
In this article we will discuss about:- 1. Definition of Photorespiration 2. Measurement of Photorespiration 3. Metabolism 4. Inhibition of Photorespiration and the Increase in Yield. Definition of Photorespiration: Photorespiration is a process or a group of processes by which certain plants release CO2 in the light. The phenomenon can be demonstrated readily if a photorespiring plant is illuminated in [...]
