-Association areas
The association areas of the cerebral cortex are not involved in primary motor or sensory functions; rather, they are involved in learning, remembering, thinking, and speaking.
Explanation;
-The cerebral cortex is divided into sensory, motor and association areas. Sensory areas receive and interpret impulses from sensory receptors , motor areas control movement of muscles (initiate impulses to skeletal muscles). Association areas are involved with more complex functions such as learning, decision making and complex movements such as writing.
-Association cortex is the cerebral cortex outside the primary areas, The majority of the cortex is composed of this area. It is essential for mental functions that are more complex than detecting basic dimensions of sensory stimulation.

Within the nodules the bacteria convert free nitrogen to ammonia, which the host plant utilizes for its development.
