Explanation:
What is mycorrhiza?
It is a symbiotic relationship between roots of higher plants and fungus. Word Mycorrhiza itself means fungus roots. Association is helpful because minerals like P, K, Cu, N, Zn and water is absorbed by the fungus from soil and give to higher plants in order to get food from the plant.
Fungus not only provides water but it also protection to plant from diseases and instead fungus gets habitat from plants.
There are two types of mycorrhiza:-
(1) Ectomycorrhiza:- In this a thick fungal mycelium layer is formed by the covering of fungus around plant roots, called as pseudo parenchymatous sheath. In Oak, Abies, Pinus this type of association is found.
(2) Endomycorrhiza:- In this no thick layer is formed around the roots of the plants. That's why they are able to provide minerals and salts directly to the cells. In Orchids this symbiotic association is found.
