PLANTS & ANIMAL TEMPERATURE TOLERANCE
Temperature/climate change and variability affects both animals and plants in a number of ways. Plants can tolerate a greater climate shift than that of animals. Animals can avoid or reduce the stress of temperature changes by using behavioural adaptations (hibernating, migrating) however, plants cannot run away from a stress and are therefore more likely to emphasize dormancy, stress-resistance, or stress-recovery mechanisms. Plants are relatively immobile and have fewer behavioural options than that of animals. Plants tolerate a broader range of environmental conditions and experience stronger selection in nature as plants can control when they open and close their stomata. The stoma is what allows the movement of gases in and out of a plant. When the weather is hotter the stomata will remain closed for a longer time, this reduces the loss of water by transpiration. Accordingly, plants tolerate broader ranges of environmental conditions than animals, simply because plants won't be able to avoid an event like temperature change that could cause stress to an organism.
