What are two types of symbiotic relationships in plant roots?
A. Bacteria in root hairs, fungi in root nodules
B. Bacteria in root nodules, fungi in mycorrhizae
C. Bacteria in mycorrhizae, fungi in root nodules
D. Bacteria in root nodules, fungi in root hairs
Homework Answers
B is correct answer because bacteria like rhizobium form symbiotic relationship with in root nodules for fixing atmospheric nitrogen. Mycorrhizae is symbiotic relationship of fungi and algae in root hair of plants where they increase nutrients and water absorption capacity of root hairs.

Micorrhizal fungi are found in many plant roots. The fungi aids the plant in uptake of water and nutrients, therefore increasing plant growth and overall health. A farmer is testing the effect of mycorrhizal fungi on the fruit production of the orange trees in his orchard. He plants 200 orange tree saplings in his orchard. Group A, 100 of the saplings, are planted normally. Group B, 100 saplings, are planted with mycorrhizal fungi on the roots. Once the trees reach...
