The solution inside a plant cell is approximately a 1% saline solution. In a 25% NaCl solution, the cytoplasm of a plant cell will
A) remain the same.
B) swell and burst from the cell membrane.
C) shrink and draw away from the cell wall.
Eliminate
D) enlarge and cause expansion of the cell wall.

Respuesta :

C, there will be a higher concentration of water inside the cell and therefore osmosis will occur. the water will move out of the cell and the cell becomes plasmolysed

The right answer is C) shrink and draw away from the cell wall.

Osmosis is the transfer of water from a dilute solution (hypotonic) to a concentrated solution (hypertonic) through a semi-permeable membrane (permeable to water, but not to large molecules in solution).

So the water inside the cell (the least concentrated medium, 1%) will go out to the most concentrated medium, which is the 25% saline solution.
