Question

An important example of interaction between fungi and certain other organisms is mycorrhizae. What is mycorrhizae?

Answer 1

mycorrhizae is really a symbiotic association between a plant and a fungus. The term mycorrhiza refers to the role of the fungus in the plant's rhizosphere, its root system. Mycorrhizae play some important roles in plant nutrition, soil biology and soil chemistry.

Step-by-step explanation:

Mycorrhizal fungi permit plants to draw more nutrients and water from the soil. They also increase plant tolerance to different environmental stresses. Moreover, these fungi play a major role in soil aggregation process and stimulate microbial activity.

Answer 2

Mycorrhizae are mutual relationship between a plant root and a fungus that colonizes the root of that plant.

Step-by-step explanation:

The fungus and the plant are mutually benefited in which the fungus help the plant in supplying water and nutrient while the plant supply food and nutrients to the fungus.

There are two kinds of mycorrhizae, the ectomycorrhizae and endomycorrhizae. Ectomycorrhicae live only on the outside of the root while endomycorrhizae has an exchange mechanish on the inside of the root. It is more intimate relationship compared to that of ectomycorrhiza.
