Why are mycorrhizal fungi superior to plants at acquiring mineral nutrition from the soil? a. hyphae are 100 to 1,000 times larger than plant rootsb. mycelia are able to grow in the direction of food. c. fungi secrete extracellular enzymes that can break down large molecules. d. hyphae have a smaller surface area-to-volume ratio than do the hairs on a plant root.

The correct answer will be option-C

Explanation:

Mycorrhizae are the symbiotic association of the fungi with higher group of plants which could be present inside and form endo relation or could be present outside and form an ectomycorrhizal association.

The mycorrhizal association provide plants benefits as the fungi hyphae are thought to secrete enzymes which help the digestion of the large biomolecules not easily digested by the plants thus providing an extra amount of nutrients to the plants and thus plants shows growth.

Thus, Option-C is the correct answer.
