Which of the following is the reason why plants wilt if they are watered with a salt solution?
A
Salt solution increases the turgor pressure inside plant cells.
B
Osmosis causes water to move out of plant cells into the salt solution.
C
Salt solution provides essential nutrients that cause wilting.
D
Osmosis causes salt to move into plant cells, dehydrating them.
Verified step by step guidance1
Understand the concept of osmosis: Osmosis is the movement of water across a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration.
Identify the conditions: In this scenario, the plant cells are surrounded by a salt solution, which has a higher solute concentration than the inside of the plant cells.
Apply the concept of osmosis: Water will move out of the plant cells into the salt solution to balance the solute concentrations on both sides of the cell membrane.
Recognize the effect on plant cells: As water leaves the plant cells, the cells lose turgor pressure, which is the pressure of the cell contents against the cell wall.
Conclude the reason for wilting: The loss of turgor pressure causes the plant cells to become flaccid, leading to the wilting of the plant.
