In which plant will you look for mycorrhiza and coralloid roots? Also, explain what these terms mean.
Mycorrhiza, which is also known as ‘fungus-root’, is a mutually beneficial relationship between a plant root and a fungus. In most cases, the fungus grows within the roots of the plants and helps the plant to absorb water and nutrients, and in return, the plant provides the fungus with food. E.g., Pinus. In some cases, the fungus could be harmful to the plants.
Coralloid Roots: These roots are associated with nitrogen-fixing cyanobacteria. In coralloid roots, the nodules are formed in large numbers, in the roots giving them a coralloid appearance. E.g. Cycas and plants of Leguminosae.
