Describe two important mutualistic relationships involving plant roots.
On May 28, 2024
Mycorrhizae: This relationship between plant roots and fungi allows the roots to absorb more water and nutrients than they could on their own. The fungi benefit from the ready supply of photosynthetically derived food.
Root nodules: This relationship between bacteria and plant roots forms a swelling (nodule) inside which bacteria can fix atmospheric nitrogen. The bacteria supply some of the fixed nitrogen to the plants, while the bacteria benefit from the ready supply of photosynthetically derived food.
