The correct option is
E Symbiotic structures living in the roots of plants that increase uptake of nutrients from the soil
Mycorrhizae is a symbiotic association between a fungus and the roots of a vascular plant. The major function of mycorrhizae is to exchange nutrients between their surroundings and their host plant. With the increase in root surface area and the protection they offer to the plant's roots, the fungus is able to acquire a lot of nutrients for its host.Therefore, the correct answer is option E.
