What is the effect of air embolism on a floral arrangement?

Air embolism occurs in the vascular system of plants when air bubbles enter the xylem, which can obstruct the flow of water and nutrients to the flower. This clogging effect significantly impacts the plant's ability to maintain turgor pressure, which is essential for keeping the petals firm and healthy. As a result, the flowers may droop, wilt, or show signs of stress, ultimately leading to a reduced lifespan for the arrangement. In contrast, options related to improved water uptake, enhanced longevity, or blooming suggest beneficial outcomes that do not occur with air embolism. Instead, the presence of air in the vascular pathways creates a barrier that hinders proper hydration, highlighting why clogging of the stem is the most accurate description of air embolism's effect on floral arrangements.
