Question

The type of solution that causes water to rush out of a cell is considered

1) Selectively permeable
2) Iso tonic
3) Hypotonic
4) Hypertonic

Answer 1

Hypertonic

Hypertonic solutions have a higher solute concentration than inside the cell. This causes water to rush out making the cell wrinkle or shrivel. This is clearly seen in red blood cells undergoing a process called crenation. Plant cells in a hypertonic solution can look like a pincushion because of what’s going on inside.
