How may a plant respond to severe heat stress? how may a plant respond to severe heat stress? by producing heat-shock proteins, which may protect the plant's proteins from denaturing by reorienting leaves to increase evaporative cooling by creating air tubes for ventilation by initiating a systemic acquired resistance response by increasing the proportion of unsaturated fatty acids in cell membranes, reducing their fluidity?
