escribe the similarities between the establishment of arbuscular mycorrhizae and legume root nodules. Which is considered to be older evolutionarily? What is the evidence for this?
Ecologists often attempt to introduce new plants to restore degraded land. In an arid climate, scientists recommend introducing plants with arbuscular mycorrhizae. How would the mycorrhizae increase the plants’ survival compared to plants without mycorrhizae?
There are some plants such as Indian pipe and orchids that do not have chlorophyll, yet they are connected to the mycorrhizal web. What would you suspect their relationship to be?
