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]
Myrmecophytes (/ m ər ˈ m ɛ k ə f aɪ t /; literally "ant-plant") are plants that live in a mutualistic association with a colony of ants. There are over 100 different genera of myrmecophytes. [1] These plants possess structural adaptations in the form of domatia where ants can shelter, and food bodies and extrafloral nectaries that provide ...
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).
[3] [page needed] Ant plants provide habitats for ant colonies high up into the forest canopy, protecting them from the elements, and in exchange, the nutrients from the ants and the debris left by the ants be absorbed in the plant's chambers. The plant in addition is protected, to some extent, from predation, especially by grazing ...
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 ...
A C3 plant uses C3 carbon fixation, one of the three metabolic photosynthesis pathways which also include C4 and CAM (described below). These plants are called "C3" due to the three-carbon compound ( 3-Phosphoglyceric acid , or 3-PGA) produced by the CO 2 fixation mechanism in these plants.
Crassulacean acid metabolism, also known as CAM photosynthesis, is a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions [1] that allows a plant to photosynthesize during the day, but only exchange gases at night.
When it oxidizes water, producing oxygen gas and protons, it sequentially delivers the four electrons from water to a tyrosine (D1-Y161) sidechain and then to P680 itself. It is composed of three protein subunits, OEE1 (PsbO), OEE2 (PsbP) and OEE3 (PsbQ); a fourth PsbR peptide is associated nearby.
