All of the following are true of mycorrhizae EXCEPT

Question

a. ectomycorrhizae extend the surface area of roots for nutrient absorption

b. endomycorrhizae colonize the outer part of the root zone

c. they are fungi that form beneficial relationships with plants

d. they enable plants to absorb soil nutrients

e. an example is the food delicacy truffles

Answer 1

Myco means fungus and rhiza means root. The word mycorrhizae means root fungus. The roots of the plant allow the fungus or mycelium to grow, and in turn the mycelium allows the plant's roots to absorb more nutrients, thus creating a symbiotic/mutually beneficial relationship.

ecto means outside and ectomyocorrhizae is the portion of the mycelium on the outside of the root that will extend the surface area of the roots. endo means inside or inner, and endomyocorrhizae is the part of the mycelium on the inside or inner portion of the plant root.

Endomyocorrhizae does not colonize the outer portion of the root zone and therefore answer choice B is incorrect.
