Osmosis help plants to absorb water from soil. Diffusion is the process by which carbon dioxide from the stomata diffuses to the leaves and then to the cells.
Explanation:
Example one - The genetic modifications in some of the plants can help in survive and adopt the osmosis in a very dry environment. They develop defense methods to handle the water loss.
Example two - Some plants in a permanent dry environment like desert have special structures like reduced leaves, sunken stomata, and so on to conserve water and thus achieves diffusion.
Another example for diffusion - loss of water vapour from leaves to the atmosphere. Another example for osmosis - the roots of the plants have high concentration than the surrounding soil and hence water flows into the roots.
