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.

- A group of researchers run an experiment to determine the effect of mycorrhizae (a fungus) on plant growth. The researchers set up three experimental groups: A large amount of mycorrhizae is applied to the plants in group 1 a smaller amount of mycorrhizae is applied to the plants in group 2, and no mycorrhizae is applied to the plants in group 3.

When there is already high soil nitrogen there is a very large cost to having rhizobial nodules. The rhizobia bacteria in the nodules fix nitrogen when there isn't enough in the soil, so when there is already high soil nitrogen there is no advantage for the pea plant to expend the extra energy housing the rhizobia. The rhizobia bacteria in the nodules use nitrogen when there isn't enough in the soil, so in conditions of high soil nitrogen the plant tries to exclude the rhizobia to keep the nitrogen for itself. When there is already high soil nitrogen there is no benefit to the plant to having rhizobial nodules, which can rob the plant of the high nitrogen supplies so that the rhizobia bacteria do not have to fix the nitrogen themselves.arrow_forward

The fungus transports water and nutrients to the cyanobacteria which then stores glucose for use by the fungus.Using a plant as your reference, which of the following statements would be the most accurate comparison to help someone understand the relationship between the fungus and cyanobacteria? The cyanobacteria acts as the ground tissue while the fungus acts as the vascular tissue. The cyanobacteria functions as the roots while the fungus is similar to the flower of a plant. The cyanobacteria acts as the meristematic tissue and the fungus acts as the ground tissues. The cyanobacteria is similar to the xylem in a plant and the fungus is similar to the phloem in a plant.arrow_forward
