1. Increased oxygen intake induces

microbial growth, enzymes break up

contaminants be process of

phytodegradation and are absorbed

with ground water into roots.

2. Particles are absorbed through cell

membranes of epidermis of root hair until they

reach the xylem.

3. Contaminant particles and water are pulled up

through the xylem from roots to shoots by force
of transpiration.

4. Stomata and guard cells regulate the

movement of water in and out of the cell
wall by the process of plasmolysis.
