In this article we will discuss about the advantages and disadvantages of transpiration. Advantages of Transpiration: 1. Ascent of Sap: Ascent of sap mostly occurs due to transpiration pull exerted by transpiration of water. This pull also helps in absorption of water. 2. Removal of Excess Water: It has been held that plants absorb far more amount of water than [...]
The key processes of biogeochemical cycling of nitrogen are: 1. Nitrogen Fixation 2. Ammonification 3. Nitrification 4. Denitrification. 1. Nitrogen Fixation: Nitrogen fixation is a process of conversion of gaseous form of nitrogen (N2) into combined forms i.e. ammonia or organic nitrogen by some bacteria and cyanobacteria. There are free-living as well as symbiotic microorganisms which fix N2 into proteins. [...]
