Question
Which one of the following pairs is correctly matched?
Rhizobium - Parasite in the roots of leguminous plants
Mycorrhizae - Mineral uptake from soil
Yeast - Production of biogas
Myxomycetes - The disease ring worm
Solution
B.
Mycorrhizae - Mineral uptake from soil
Mycorrhiza is an example of mutualism. Mutualism is an interaction between two or more species where fitness is increased through direct interaction. It is an association between a fungus and the root of a higher plant. eg. Pine, Birch.
The fungus obtains shelter and food from root and helps the root in absorption of water, dissolution and absorption of inorganic nutrients locked in organic matter (especially nitrogen and phosphorus) and protection from other fungi.
