Question

Mycorrhizae are useful for plants mainly due to their one of the following attributes.

• A. Fixing atmospheric nitrogen
• B. Enhanced absorption of nutrients from soil
• C. Killing insects and pathogens
• D. Providing resistance against abiotic stresses

Answer 1

Answer: (B)

Enhanced absorption of nutrients from soil

A mycorrhiza is defined as a symbiotic relationship between the roots of plants and fungi. It enhances the inorganic nutrient uptake by plants. It also has ability to provide protection to plants from heavy metals by limiting translocation of metals into above ground plant parts. Due to nutrient uptake enhancing properties of mycorrhizae, the ability of it to stimulate plant growth has been used in agriculture and forestry.

So, the correct answer is 'Enhanced absorption of nutrients from soil'
