Question

All of the following involves osmosis except

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

Answer 1

The correct option is B Water passing from a xylem vessel element to xylem vessel element above it.

Water passing from a xylem vessel element to xylem vessel element above it due to the transpiration pull exerted by the mesophyll cells. However, the transfer of water from the soil to the root is due to osmosis.

Therefore, the correct answer is option B.
