Not exactly....rather, they transpire...
HOW TRANSPIRATION WORKS
Covered with a water-impermeable cuticle membrane on their top surface, leaves discharge or evaporate water through stomata, or pores, on their undersides. Stomata can open discharge water and close to conserve it. When stomata are open, the leaves draw water up through plant tissues from the roots. The suction created by evapotranspiration both cools plant tissues and provides the means by which nutrients absorbed by roots are distributed throughout plant cells. Water vapor is required for leaves to absorb carbon dioxide which is critical to photosynthesis. Transpiration occurs as a regular self-feeding behavior even when temperatures are moderate. Although usually triggered by sunlight, the stomata of some plants in high-temperature desert climates open only at night when air is cooler.
FROM YOUR FRIENDS, THE LATE BLOOMERS....BLOOM WHERE YOU ARE PLANTED!
