Detailed explanation-1: -The word “mycorrhiza” means fungal root. To be more specific, mycorrhizae are fungi that have a symbiotic relationship with the roots of many plants.

Detailed explanation-2: -Nutrients and water Not only do the fungal threads help to bring water and nutrition into the plant, but they also can store them for use when rainfall is sparse and temperatures are high. When organic matter (compost) is added to improve a soil, mycorrhizae are important in making its nutrients available.

Detailed explanation-3: -Instead, fungi grow as masses of narrow branched threads called hyphae. These hyphae have thin outer walls, and their food, water and oxygen need to move across the wall into the living fungal cell – a process called absorption.

Detailed explanation-4: -The increased mineral uptake by roots of plants with mycorrhizae is traceable largely to their extensive absorbing surface. The fungal hyphae often extend into the portion of the soil that is not penetrated by roots or root hairs.
