NEET Biology question
Not in NEET syllabus
Match the following columns and choose the correct option.
List-I: (A) Water potential of 10% salt solution (B) Pressure potential in a normal cell (C) Pressure potential in a plasmolysed cell (D) Metric (matric) potential on the surface of the wood
List-II: (1) Positive (2) Negative (3) Positive (4) Negative (5) Zero
Answer: (A)
Solution
A concentrated 10% salt solution has a strongly negative water potential (A–2, Negative). The pressure potential of a normal, turgid cell is positive, as the protoplast pushes against the wall (B–3, Positive). In a plasmolysed
