- Water molecules are stored in the spaces between the plant's tissues. As these molecules leave, they pull others along with them along pathways called xylem. During the process of photosynthesis, the way in which a plant creates its own food, the water molecules not used exit the leaves through tiny holes called stomata.
- Plants take in water through their roots and leaves. They transpire to cool themselves in hot weather, when the humidity drops, or when the sunlight they are exposed to intensifies. High humidity slows transpiration, as the damp air is too saturated to make room for more moisture.
- During dry spells, plants give off less water as a survival mechanism. The same applies to plants, such as cacti, that grow in arid regions and store water and release very little back into the atmosphere.
