The mycorrhiza is a structure that is formed for a symbiotic association of fungi and gymnosperms. The fungus in this is associated with the roots of higher plants. They are generally the gymnosperms and angiosperms and this structure together is known as mycorrhiza. It is of two types that are Ectomycorrhizal and Endomycorrhiza. In ectomycorrhiza, the fungal part is external in nature. It forms a woolly covering on the external surface of the roots and thus helps in forming a network of mycelium. This network is formed in the intercellular spaces of the cortex. Basidiomycetes and zygomycetes are the majority of the fungal partners. In the endomycorrhiza, the hyphae are present in the tissues of the roots. It then spreads intracellularly and also intercellularly. The cell wall is broken by the fungus and it enters the cortex region.
