When a bacterial cell is placed in a solution with higher solvent concentration and low solute concentration, relative to it's cellular contents, this osmotic possibility is _______Group of answer choiceshypotonichypertonicisotonic
Solution
The correct answer is "hypotonic".
Here's why:
Osmosis is the movement of solvent (usually water) from an area of lower solute concentration to an area of higher solute concentration.
When a bacterial cell is placed in a solution with a higher solvent concentration (meaning lower solute concentration) compared to its cellular contents, the solvent will move into the cell in an attempt to balance the solute concentrations.
This type of solution is referred to as hypotonic. In a hypotonic solution, the concentration of solutes is greater inside the cell than outside of it, so water moves into the cell.
On the other hand, a hypertonic solution has a higher concentration of solutes outside the cell than inside, so water moves out of the cell. An isotonic solution has equal concentrations of solutes inside and outside the cell, so there is no net movement of water.
