Question

Quizplus · Accepted Answer

Mycorrhizae are specialized fungi that form a symbiotic association with plant roots, increasing their ability to absorb nutrients, including phosphorus and micronutrients like magnesium. The mycorrhizae effectively expand the root system by extending their hyphae (thin, thread-like structures) into the soil, increasing the surface area for nutrient uptake. Therefore, if Mg²⁺ is in low abundance, plants can form mycorrhizae to increase their absorption of this nutrient.
