A)
Solution \[(\psi )\] A \[-\,700\,kPa\]
B)
Solution \[(\psi )\] B \[-\,1000\,kPa\]
C)
Solution \[(\psi )\] C \[-\,400\,kPa\]
D)
Solution \[(\psi )\] D \[-\,200\,kPa\]
Correct Answer: B
Solution :
The tissue has a water potential of \[-700kPa.\] 'A' is isotonic to the tissue. Addition of solute tends to lower the water potential. Therefore, the most negative (hypertonic) will have more solutes in it, causing water to move out of the tissue into the solute. This would be the answer [b] \[(-1000kPa).\] [c] and [d] are both hypotonic to the tissue, causing water to move in, making it more turgid instead.
