Rhizobia and Mycorrhizae Share All of the Following Features Except

Question

Rhizobia and mycorrhizae share all of the following features except
A) they both benefit by receiving carbohydrate from the plant.
B) many are host-specific.
C) they both become parasitic in nutrient-rich environments.
D) they both enhance the growth of most plants.
E) they both are found in most ecosystems of the world.

Accepted Answer

Rhizobia and mycorrhizae enhance plant growth and receive carbohydrates from the plant but they do not become parasitic in nutrient-rich environments. In fact, they have a mutualistic relationship with the plant and help it to acquire nutrients. While many rhizobia and mycorrhizae are host-specific, they are not found in all ecosystems of the world, as some environments may not support their growth.
