Please answer question number 20
Dear student.
Regards.
Mycorrhizae is the symbiotic association between the fungi and the roots of some plants. Mycorrhizal roots show a wooly covering and lack root caps and root hairs unlike normal roots. The fungal partner obtains nourishment from the cortical cells of the root and also depends upon the plant for shelter. The mycorrhizal hyphae help in increasing the surface area for absorption, so enable the plants in getting the enhanced supply of water, nitrogen, phosphorus and other minerals from the soil.
