    Trees Water
AI Thread Summary
The discussion centers on the mechanisms by which trees transport water from their roots to their leaves, emphasizing the roles of transpiration, capillary action, and the physical properties of water. Transpiration involves the evaporation of water from leaves, creating a negative pressure that pulls water upward through the plant's vascular system. This process is complemented by the capillary effect, which allows water to move through small spaces in the plant's xylem. As water is lost through evaporation, roots absorb additional water from the soil, maintaining a continuous flow. Understanding these processes is crucial for comprehending plant physiology and water dynamics in ecosystems.

How does a tree get tons of water from bottom to top?
 
Biology news on Phys.org
It is all about transpiration, capillary effect and water physical properties.

Plants evaporate a large amount of water through their leaves. As the water evaporates, it pulls water into the leaves through the stems and roots. The lost water is replaced by the roots' absorbing additional water from the soil.
