Beetroot Cells with High temperatures and low pH solutions Friday 15th March 2013 Abstract (50) The aim of this investigation was to study the effects of temperature and a low pH solution on beetroot cells. Introduction (200) The general belief amongst our group members was: an increase in temperature will damage the permeability of the plasma membrane. Also‚ the heat will break away the permeability. If the pH solution is 7 or greater there will be no change but the lower the pH the more proteins
