Endomycorrhiza is a type of symbiotic relationship between fungi and plant roots. In this association, the fungi penetrate the root cells, forming structures called arbuscules, which help in nutrient exchange. This relationship enhances the plant's ability to absorb water and essential minerals, such as phosphorus, from the soil. These fungi are crucial for many plants, especially in nutrient-poor soils. They improve plant health and growth, making them more resilient to environmental stresses. Endomycorrhiza is commonly found in many species, including trees and crops, playing a vital role in ecosystems and agriculture.
