Prepare for NEET Biology Transport in Plants with MCQs & PYQs on NEET.GUIDE. Access free practice, previous year questions, and expert guidance to understand xylem, phloem, and movement of water.
Two identical plant cells are placed in separate solutions. Cell A is placed in a 1M sucrose solution, and Cell B is placed in a 1M NaCl solution. Which cell will experience greater plasmolysis, assuming ideal conditions and complete dissociation of NaCl?
Cell A
Cell B
Both cells will plasmolyze equally
Neither cell will plasmolyze
Two solutions, A and B, are separated by a selectively permeable membrane. Solution A contains 10% sucrose, and Solution B contains 20% sucrose. In which direction will the net movement of water occur?
From Solution A to Solution B
From Solution B to Solution A
There will be no net movement of water.
The sucrose will move from Solution B to Solution A.
    When sugars enter sieve tubes, water flows by osmosis, resulting in
    Water potential
Osmotic gradient
Turgor pressure
DPD
    Which of the following has maximum water potential?
    Pure water
2% sucrose solution
4% glucose solution
10% sodium chloride solution
What happens when concentration of solutes decreases in guard cells?
    Water potential increases
Osmotic pressure increases
Water potential decreases
None of the above
    If solute particles are added in pure water, its diffusion pressure will be
    Increased
Decreased
Remain constant
Become less than zero
Water potential gradient decides?
Direction of movement of water
Concentration of Solute
Rate of movement of water
1 and 3
