Front

What does hypertonic mean in relation to a cell?

Back

Front

What does hypotonic mean in relation to a cell?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell.

Front

What does isotonic mean?

Back

Isotonic means equal concentration of solutes inside and outside the cell.

Front

What is the effect of an isotonic solution on a cell?

The cell remains the same size because water moves equally in and out.

Front

What is a semi-permeable membrane?

Back

A semi-permeable membrane allows certain substances to pass through while blocking others.
