Mineral nutrition:

The fungal component helps in phosphate mobilisation thus providing mineral nutrition to the plant.


Translocation:

Translocation is the process of transport of organic solvents in the phloem of the plants


Gaseous exchange:

The major sites of gaseous exchange are through the stomatal pores present in the leaves.
