Which one of the following helps in absorption of phosphorus from soil by plants?

(a) Rhizobium

(b) Frankia

(c) Glomus

(d) Anabaena

Answer: (c)

Some fungi 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.
