Detailed explanation-1: -Correct option: c 2Explanation:Water could travel to the endodermis layer via the apoplast pass through the outer endodermis cell membrane and enter the stele apoplast by diffusing through the inner endodermis membrane.

Detailed explanation-2: -In pathway, water crosses at least two membranes for each cell in its path (i.e., plasma membrane on entering and exiting).

Detailed explanation-3: -The transmembrane (or vacuolar) pathway is the route followed by water that sequentially enters a cell on one side, exits the cell on the other side, enters the next in the series and so on. In this pathway, water crosses at least two membranes for each cell in its path (the plasma membrane on entering and on exiting).

Detailed explanation-4: -Water can pass through biological membranes via two pathways: simple diffusion through the lipid bilayer, or water-selective facilitated diffusion through aquaporins (AQPs).

Detailed explanation-5: -Osmosis is the net movement of water across a selectively permeable membrane driven by a difference in solute concentrations on the two sides of the membrane.
