Endothermy in Plants
• Skunk cabbage– plants in family Araceae use metabolic heat to
warm flowers…are thermogenic– infloresence is 15-35°C higher than environment;
melts snow– heat produced by high rate of respiration (starch
transported from root to inflorescence)– metabolic rate varies with environmental
temperature
