Sugar Dust Explosion

Hyper, Hypo, Iso (Tonic)*Hyper(tonic) = higher concentration of solute compared to surroundings

Cells will shrink

Hypo(tonic) = lower concentration of solute compared to surroundings

Cell will swell

Iso(tonic) = equal concentration of solute compared to surroundings

Cells won’t change
