Correlate the movement of materials across the cell membrane with the terms hypertonic, hypotonic, and isotonic.
Solution
If a cell is kept in a hypotonic solution will swell. Alternatively, if a cell is placed during a hypertonic solution, the cell will shrink. In an isotonic solution, the cell will be the same
Complete answer:
Three terms hypertonic, hypotonic, and isotonic are used to describe whether a solution will cause water to move into or out of a cell:
If a cell is kept in a hypertonic solution, there will be an overall flow of water out of the cell, and the cell will lose volume. A solution is going to be hypertonic to a cell if its solute concentration is above that inside the cell, and the solutes cannot cross the membrane.
If a cell is placed during a hypotonic solution, there'll be a net flow of water into the cell, and the cell will gain volume. If the solute concentration outside the cell is less than inside the cell, and the solutes cannot cross the membrane, then that solution is hypotonic to the cell.
If a cell is placed in an isotonic solution, there'll be no net flow of water within or out of the cell, and the cell’s volume will stay stable. If the solute concentration outside the cell is equal to within the cell, and the solutes cannot pass the membrane, then that solution is isotonic to the cell.
Additional information:
The ability of an extracellular solution to form water enter or out of a cell by osmosis is understood as its tonicity. Tonicity is a bit different from osmolarity because it takes under consideration both relative solute concentrations and the cell membrane’s permeability to those solutes.
Note:
The semipermeable membrane is a biological membrane, which functions by permitting the movements of certain molecules or ions to pass through it. Reverse osmosis is a natural event that takes place in the opposite direction of natural osmosis. This type of osmosis is employed for removing the bulk of contaminants from water by pushing the water struggling through a semipermeable membrane.
