Is the 15 percent NaCl solution hypertonic isotonic or hypotonic relative to the cytoplasm?
Asked in Microbiology, Cell Biology (cytology)
A solution that contains a lower solute concentration than the cytoplasm of a cell is?
Does a cell in an isotonic solution lose water or gain water?
The cell will not loose or gain water. An isotonic solution means that the amount of solutes outside the cell is similar or equal to the amount of solutes inside the cell. Water is moving by osmosis both in and out of the cell at equal rates; the net movement of water is zero. A cell will lose water in a hypertonic solution (more solute in the surrounding environment) and gain water in a hypotonic solution (more solute in the cellular environment). Whether or not a solution is hypertonic, hypotonic, or isotonic is relative to the environment in the cell.
