Answer:
true,The ability of an extracellular solution to make water move into or out of a cell by osmosis is known as its tonicity.
Explanation:
The ability of an extracellular solution to make water move into or out of a cell by osmosis is known as its tonicity. Tonicity is a bit different from osmolarity because it takes into account both relative solute concentrations and the cell membrane's permeability to those solutes.
