Which statement about mycorrhizae is true?

Question

Quizplus · Accepted Answer

Mycorrhizae are mutualistic associations between fungi and the roots of most plants. They increase the functional surface area of a root system by forming a network of hyphae that extend beyond the root and can access nutrients and water that the plant may not otherwise be able to reach.

Option B is incorrect because mycorrhizae involve an interaction between fungi and plants rather than bacteria. Option C is also incorrect because mycorrhizae are a common and widespread phenomenon in most terrestrial ecosystems. Option D is incorrect because mycorrhizae do not spread via plant seeds, but rather through fungal spores or by directly colonizing the roots of neighboring plants. Option E is incorrect because mycorrhizal structures do not exclude oxygen, but rather the opposite - they enhance the uptake of oxygen by the plant roots.
