The plant has evolved to grow a caudex as the benefits of ants outweighs the costs. [4] Ant defecation is beneficial to the plant as the plant can absorb nutrients from it as well as the gases the ants release. Ants have high diets in animal tissue which is correlated to a faster release of nutrients and they trim encroaching vegetation. [4]
Tschinkel standing next to a plaster cast of a Pogonomyrmex badius. (Photo by Charles F. Badland, 2006) Initially an experimental biologist observing ants' behavior above ground or in the laboratory, Tschinkel became deeply invested in understanding the architectural complexity of their subterranean homes, which became "almost an obsession."
So, in the presence of light, synthesis of food is called 'photosynthesis'. Noncyclic photophosphorylation through light-dependent reactions of photosynthesis at the thylakoid membrane. In the process of photosynthesis, the phosphorylation of ADP to form ATP using the energy of sunlight is called photophosphorylation. Cyclic ...
In parallel, plant physiologists studied leaf gas exchanges using the new method of infrared gas analysis and a leaf chamber where the net photosynthetic rates ranged from 10 to 13 μmol CO 2 ·m −2 ·s −1, with the conclusion that all terrestrial plants have the same photosynthetic capacities, that are light saturated at less than 50% of ...
Light-dependent reactions of photosynthesis at the thylakoid membrane. Photosystems are functional and structural units of protein complexes involved in photosynthesis. Together they carry out the primary photochemistry of photosynthesis: the absorption of light and the transfer of energy and electrons.
A germination rate experiment. Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. [1]Plant physiologists study fundamental processes of plants, such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed ...
By replenishing lost electrons with electrons from the splitting of water, photosystem II provides the electrons for all of photosynthesis to occur. The hydrogen ions (protons) generated by the oxidation of water help to create a proton gradient that is used by ATP synthase to generate ATP .
This exchange of metabolites is essential for C 4 photosynthesis to work. Additional biochemical steps require more energy in the form of ATP to regenerate PEP, but concentrating CO 2 allows high rates of photosynthesis at higher temperatures. Higher CO 2 concentration overcomes the reduction of gas solubility with temperature (Henry's law).
