What is the advantage of the fungal symbiont in mycorrhiza?
Options
- AAbsorbing phosphorus from soil
- BPassing phosphorus to the plant
- CFixing atmospheric nitrogen into organic forms
- DIncreasing soil fertility
Correct answer
A. Absorbing phosphorus from soil
Step-by-step solution
Fungi are also known to form symbiotic associations with plants (mycorrhiza). Many members of the genus Glomus form mycorrhiza. The fungal symbiont in these associations absorbs phosphorus from soil and passes it to the plant. Plants having such associations show other benefits also, such as resistance to root-borne pathogens, tolerance to salinity and drought, and an overall increase in plant growth and development.
