In a study of plant response to climate change, researchers sampled 537 plant species in climate zones around the world and found that tall plants had wider water-conducting vessels than short plants, and that, perhaps consequently, tall plants were more vulnerable than short plants to water-blocking embolisms caused by drought or cold, according to the authors.
