Plant structural component of the plant. Chlorophyll, a green-colored, magnesium-containing pigment is essential to this process; it is generally present in plant leaves, and often in other plant parts as well. Parasitic plants, on the other hand, use the resources of their host to provide the materials needed for metabolism and growth. Plants usually rely on soil primarily for support and water (in quantitative terms), but they also obtain compounds of nitrogen, phosphorus, potassium, magnesium and other elemental nutrients from the soil. Epiphytic and lithophytic plants depend on air and nearby debris for nutrients, and carnivorous plants supplement their nutrient requirements,
Plant to plant communication via mycorrhizal networks Plant to plant communication via mycorrhizal networks Plant to plant communication via mycorrhizal networks refers to connections through mycorrhizal networks that facilitate communication between plants of the same or different species. Mycorrhizal networks allow for the transfers of signals and cues between plants which influence the behavior of the connected plants by inducing morphological or physiological changes. The chemical substances which act as these signals and cues are referred to as infochemicals. These can be allelochemicals, defensive chemicals or nutrients. Allelochemicals are used by plants to interfere with the growth or development of other plants or organisms, defensive chemicals can
