Question

What is the function of mycorrhizac for plant?

Answer 1

A mycorrhiza (typically seen in the plural forms mycorrhizae or mycorrhizas, Greek for fungus roots) is the result of a mutualistic association between a fungus and a plant. This mutualism takes place at the root level, where individual hyphae extending from the mycelium of a fungus colonize the roots of a host plant, either intracellularly or extracellularly.

This mutualistic association provides the fungus with a renewable source of food through access to fixed carbon (sugars) from the plant photosynthate. These are translocated to the root tissues from their source location (usually leaves), and then to the fungal partners. In return, the plant gains the use of the mycelium's tremendous surface area to absorb mineral nutrients from the soil. It is believed that the mycelia of mycorrhizal networks have better mineral absorption capabilities compared to plant roots. An example of this is the manner in which phosphate ions are tightly bound to iron oxides in many soils. Plant roots are generally incapable of accessing these phosphorus sources (which can be large and are termed sinks), yet mycorrhizal mycelia can access these forms of phosphorus. The mechanisms of increased absorption are both physical—mycorrhizal mycelia are much smaller in diameter than the smallest root hair and thus are able to explore a greater volume of soil and have a much larger surface area for absorption—and chemical—the cell membrane chemistry of fungi is different from that of plants. Mycorrhizae are especially beneficial for the plant partner in nutrient poor soils.

Answer 2

infact this is the association of fungus and plants. in which both get benifit in a process called mutualisam.
fungs is present undreground attached to the roots of the plant and gets food from the plant. in return it provides a huge surface area to the plant for the absorption of water and nutrients.

Answer 3

There is increasing evidence that inorganic fertilisers disrupt the connections between tree roots and fungal mycorrhizac, thereby making trees more susceptible to stress from pathogens and drought. The risk probably increases exponentially the closer to trees that these fertilisers are used.
