What is the term given to the mutualistic association between fungi and the roots of higher vascular plants?

💡 Solution & Explanation

Mycorrhiza represents a symbiotic mutualistic association between soil fungi and the roots of higher vascular plants, where the fungal partner enhances the host plant's absorption of water and immobile nutrients like phosphorus. In contrast, lichens are symbiotic associations involving algae and fungi, while Rhizobium forms nitrogen-fixing nodules specifically on the roots of legumes. Plant physiology concepts related to symbiotic interactions frequently feature in competitive biology questions.
