When this occurs, they form gaseous molecules of water vapor, which float to the surface as bubbles and travel into the air. Instead of air, the bubbles in a boiling pot of water are actually made up of water — it's just water in its gaseous state!
Xerophytes are plants that have adapted to arid climates. They have evolutionary developed adaptations to reduce the rate of transpiration so as to conserve water.
Among the adaptations include; thick cuticle, small, thick leaves, reducing the surface area relative to the volume of the leaf, etc.
Additionally, they use CAM pathway as an alternative photosynthetic pathway to minimize water loss.
