NEET Biology question
Not in NEET syllabus
Two cells (A and B) have osmotic potential and pressure potential −18 bars and 8 bars, and −14 bars and 2 bars respectively. What will be the direction of water flow?
Answer: (A)
Solution
Water potential Ψw = Ψs + Ψp: cell A = −18+8 = −10 bars; cell B = −14+2 = −12 bars. Water moves from the higher (less negative)
