Question

tonicity in cells refers to the concentration of solute in a solution outside of a cell, relative to multiple choice the swelling of the cell. the number of cell fragments inside the cell. the solute concentration of the cytoplasm inside the cell. the permeability of the cell membrane.

Explanation:

Tonicity is about the relative solute - concentration gradient across the cell membrane. It compares the solute concentration outside the cell to that inside the cytoplasm of the cell, which affects water movement via osmosis.

Answer:

C. the solute concentration of the cytoplasm inside the cell
