Chapter 30, Problem 10TYK
In a college greenhouse, a new employee observes fuzzy mycorrhizae in the roots of all the plants. Destroying no part of the plants, she carefully removes the mycorrhizae. The most immediate result of this “cleaning” is that the plants cannot:
a. carry out photosynthesis.
b. absorb water through their roots.
c. transport water up their stems.
d. extract as much nitrogen from soil.
e. store carbohydrates in their roots.

Students have asked these similar questions
The greatest difference in health between two groups of plantsof the same species, one group with mycorrhizae and one groupwithout mycorrhizae, would be in an environment(A) where nitrogen-fixing bacteria are abundant.(B) that has soil with poor drainage.(C) that has hot summers and cold winters.(D) in which the soil is relatively deficient in mineral nutrients
Why are fungal insecticides an attractive alternative to chemical pesticides for growing food crops? a. Human consumption of fungal insecticides would not make a person sick, but ingestion of chemical pesticides can be harmful to humans. b. A single fungal insecticide would kill a wider variety of insects than a chemical pesticide. c. Fungal insecticides can eliminate both harmful insects and plant pathogens, while chemical pesticides only kill insects. d. Fungal insecticides will decompose dying plants, enhancing the nitrogen content of the soil, while chemical pesticides are not decomposers.
A. Explain one reason why a farmer or home gardener might want to use a commercial mycorrhizae product when growing plants.
B. Describe something that would need consideration in order to produce a successful mycorrhizal product.
