Question

Choose the correct answers from the alternatives given :
In which one of the following processes the phenomenon of osmosis is not involved

• A. Water entering a mesophyll cell from xylem vessel element
• B. Water passing from root hair to adjacent cells
• C. Water from soil entering a root hair
• D. Water passing up a xylem vessel element to xylem vessel above it

Answer 1

The correct option is D Water passing up a xylem vessel element to xylem vessel above it

Osmosis is the movement of solvent from its higher concentration to its lower concentration across a semipermeable membrane. Movement of water through xylem element to xylem vessels above it occurs due to the cohesive force between the water molecules, suction pressure and transpiration pull.

So the correct answer is "Water passing up a xylem vessels element to xylem vessel above it".
