There are two specific cycles that enable plants to get their nutrients from the soil; they are the cation exchange and the nitrogen cycle. The first cycle that permits plants to get nutrients from the soil is the cation exchange. The cation exchange is a process where cations are removed from the particles within the soil by other cations1 .
The process whereby atmospheric nitrogen is reduced to ammonia in the presence of nitrogenase (found naturally in microorganisms viz. Rhizobium, free living Azotobacter etc) is called Biological nitrogen fixation (BNF). The best example for the symbiotic
Phosphate rock is THEN mixed with sulphuric acid to produce weak phosphoric acid. This phosphoric acid is mixed with various other minerals to produce liquid or solid fertilizers. Theses process vary with respect to the fertilizer being produced. Frequently manufactured fertilizers are triple superphosphates (SSP, TSP) and ammonium phosphates (MAP, DAP). By 2015, phosphate fertilizer production is expected to be 57.6 million tons.
This experiment is an attempt to investigate the amount of water potential across root storage plant species. The root storage plant species that shall be used are the carrot and the potato and the method that shall be used is known as Chardakov’s method. Water potential is the tendency of water to enter or leave a cell. Water moves from an area or region of low water potential to an area of high water potential. It is important to note that the highest water potential is 0(the water potential of pure water) and the other water potential values are in negative numbers .
The long-term reactions are the pozzolanic reactions. The addition of lime to soil produces a highly alkaline environment, due to the OH- anions from the hydration of lime, which gives rise to a slow solution of silica and alumina from clay particles (Kinuthia et al.1999; Mathew and Rao, 1997). The cementation process develops from the reaction between calcium present in lime and dissolved silica and alumina from soil, forming calcium-silica-hydrates (CSH), calcium alumino-hydrates (CAH), and calcium-alumino-silica-hydrates (CASH) (Nalbantoğlu and Tuncer,
3. GROWTH AND CELL DIVISION OF PHYTOPLANKTON Phytoplanktons have diversity and are of both the types prokaryotic and eukaryotic. Cell division is the vital process for regeneration. Prokaryotic forms of phytoplankton which comes under domain bacteria divide by basic process of cell division like binary fission. Eukaryotic phytolanktons which comes under domain eukarya are divide by the process of mitosis.
Amarant has a hyper accumulator that capable to uptake high concentration of contaminant without damaging its growth. (Khoramnejadian, S.,2014). The mechanism involved in phytoremediation is plant could take up heavy metal, solvent, aromatic carbon, and other contaminants from soil, sludge and water. However phytoremediation is not suitable for high contaminated sites, limited to the surface area.
[reference] Experimental and theoretical work have demonstrated large effects of macromolecular crowding on the thermodynamics and kinetics of many biological processes. The influence of macromolecules on protein stability is thought to arise from two phenomena: hard-core repulsion and chemical interactions. The repulsive interaction is always stabilizing because it involves only the arrangement of molecules and they affect the entropic component of
In present time, many research has been done on the toxicity of cadmium in microorganisms. Microorganisms release many types of organic and inorganic substances by which they can detoxify
The most important intracellular buffer systems are phosphate and protein. The most important plasma buffer systems are carbonic acid-bicarbonate and the protein hemoglobin. The carbon acid-bicarbonate buffer is a major extracellular buffer and operates within the lungs and the kidneys. To decrease the amount of carbonic acid the lungs function to remove carbon dioxide and leave water remaining. In turn, the kidneys use the carbon dioxide and water to create or absorb bicarbonate.
