Some plants have genetic modifications to tackle dry conditions and some plants in desert kind of atmosphere have specially adopted structures for effecting osmosis and diffusion.
Explanation:
Osmosis help plants to absorb water from soil. Diffusion is the process by which carbon dioxide diffuses to the leaves and then to the cells.
The genetic modifications in some of the plants can help in survive and adopt the osmosis in a very dry environment. They also develop defense methods to handle the water loss.
Some plants in a permanent dry environment like desert have special structures like reduced leaves, hairs, sunken stomata, and so on to conserve water.
