Question

What is the structural feature of mycorrhiza that enables enhanced mineral absorption?

Options

• The formation of root nodules filled with nitrogen-fixing bacteria

• The fungal partner significantly extends the absorptive surface of the root system

• The conversion of atmospheric nitrogen into ammonia

• The solubilization of inorganic phosphates through bacterial enzymes

Answer 1

In mycorrhiza, the fungal partner forms an intimate association with plant roots and significantly extends the absorptive surface area of the root system. This increased surface area allows for enhanced absorption of phosphorus and other minerals from the soil, as well as providing protection against pathogens.
