Q. Osmosis is not related to diffusion of water from :
(a) One cell to another
(b) Soil to root
(c) Xylem to Xylem
(d) None of these
Solution :
Correct option : C Osmosis is the process of flow of fluid from higher to lower concentration through the semi-permeable membrane. The wall of xylem vessels behaves as the semi-permeable membrane so diffusion of water from one xylem vessel to another xylem vessel can be called the phenomenon of osmosis.
In all other three cases, there is no presence of semi-permeable membrane so, it is the simple diffusion process.
So, the correct answer is the ‘xylem to xylem ‘.
