Vedclass · Answer

(A) The plasma membrane of a cell acts as a selectively permeable membrane. When water and mineral salts move from the $Soil$ into the $root  hair$, they must cross the plasma membrane of the root hair cells. This process involves the selective uptake of specific ions and water molecules, demonstrating the property of selective permeability. While other movements also involve membranes, the initial entry from the soil into the living root hair cell is the most classic example of this biological phenomenon.

An example of a selectively permeable membrane can be best deduced from the passage of water and mineral salts from:
