This can be answered with the help of describing osmosis and diffusion in plants. The motion of molecules through the semi-permeable membrane is osmosis. In diffusion, motion of molecules is direct and does not need a semi-permeable membrane.
Explanation:
- In plants, 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 develop defense methods to handle the water loss. Some plants in a permanent dry environment like desert have special structures like reduced leaves, sunken stomata, and so on to conserve water.
- Osmosis happens only in liquid medium. Diffusion happens in any medium - solid, liquid, and gases.
I think it does make up all of the body tissues and organs.
