If you have two adjacent cells, cell A has an osmotic potential of -2.1MPa and 0

Question

If you have two adjacent cells, cell A has an osmotic potential of -2.1MPa and 0.5MPa pressure potential; cell B has a osmotic potential of -4MPa and a pressure potential of 1MPa.

Which direction will water flow?

If osmosis occurs between the two cells from the previous question, then which is TRUE?

A. B's turgor will decrease

B. A will reach an equilibrium water potential more negative than -3MPa

C. A's turgor will decrease

D. A's osmotic potential will increase

A. B's turgor will decrease

B. A will reach an equilibrium water potential more negative than -3MPa

C. A's turgor will decrease

D. A's osmotic potential will increase

Explanation / Answer

Normaly the water move from hypotonic solution to hypertonic solution across the semi-pemiable membrane

Here B cell osmotic potential is less so water move from B cell to A because of that B's turgor will decrease

The correct option is A
