What are Mycorrhizae (Mycorrhiza)?
Answers
Mycorrhizae is a symbiotic association between roots of higher plants and fungi
NCERT based Answer for Class 11 Biology Students
Mycorrhizae:
Symbiotic association of fungus with root system.
Fungal filaments form network around roots.
Hyphae have very large surface area that absorb mineral ions and water from soil in large volume and provide these to plant.
In turn, roots provide sugars and N- containing compounds to fungi.
Some plants have an obligate association with mycorrhizae. E.g., Pinus seeds cannot germinate without presence of mycorrhizae.
Advantages of mycorrhizal association:
Enhanced plant efficiency in absorbing water and nutrients from the soil.
Reduced fertilizers and irrigation requirements.
Increased drought resistance.
Increased pathogen resistance by competing with root pathogens for space and resources.
