Concept explainers
To describe: The importance: Mycorrhizae in colonization of land.
Concept introduction: The term Mycorrhizae is derivative of Greek words "mukés", which means
Mycorrhiza forms symbiotic relationships with roots of the plant. They form close association with the plant roots in order they can draw nutrients from the soil. This association between fungus and plant promotes plant growth. Similar associations might have been essential for the earliest land plants that did not have roots. Thus, beneficial relationships between plants and fungi existed from the early period and thus helped plants in colonization of land.

- Ecologists often attempt to introduce new plants to restore degraded land. In an arid climate, scientists recommend introducing plants with arbuscular mycorrhizae. How would the mycorrhizae increase the plants’ survival compared to plants without mycorrhizae?arrow_forwardDescribe the important ecological role of mycorrhiza.arrow_forwardHow do mycorrhizae function as biofertilisers? Explain with example.arrow_forward
