TURGOR CHEMISTRY. “Floral movements are based on changes in osmotic pressure in cells that do not elongate, or on differential elongation growth. Both involve an increase in osmotic pressure, followed by water uptake. Prior to opening, osmotic solute levels increased, for example by the conversion of polysaccharides (starch or fructan) to monosaccharides, and/or the uptake of sugars from the apoplast.”
