NEET Biology: Class 11, Chapter 11: Transport in Plants questions with solutions

Q1. If a plant cell is placed in deionised water, the water potential of that cell becomes

1. More positive because pressure potential becomes more positive
2. More positive because pressure potential becomes more negative
3. More negative because pressure potential becomes more negative
4. Less negative because pressure potential becomes more positive

Answer: Less negative because pressure potential becomes more positive

Deionised water has a higher water potential than the cell, so water enters by osmosis. This increases the cell’s pressure potential (turgor), which makes the cell’s overall water potential less negative.
