[Campbell Biology P.870] Mycorrhizae enhance plant nutrition mainly by | Practice Question

Mycorrhizae enhance plant nutrition mainly by

  • A: absorbing water and minerals through the fungal hyphae.
  • B: providing sugar to root cells, which have no chloroplasts.
  • C: converting atmospheric nitrogen to ammonia.
  • D: enabling the roots to parasitize neighboring plants.

Explanation

Mycorrhizal fungi extend their hyphae extensively into the soil, vastly increasing the surface area for the absorption of water and mineral nutrients, making them more available to the plant than roots alone could achieve.
