    This hyperpolarization of the membrane allowed the accumulation of charged potassium (K +) ions and chloride (Cl −) ions, which in turn, increases the solute concentration causing the water potential to decrease. The negative water potential allows for osmosis to occur in the guard cell, so that water enters, allowing the cell to become turgid.

    When grass is cut or damaged, lipoxygenase enzymes begin a breakdown of membranes in the plant's cells, producing linoleic and linolenic acids.Exposure to oxygen leads to the formation of cis-3-hexenal, which rapidly breaks down to cis-3-hexenol (leaf alcohol) and (E)-2-hexenal (leaf aldehyde).
