¿Qué son las plantas?: transpiración

The video explains the process of respiration in humans and plants. Humans inhale air and exhale gases, including water vapor, which is visible on cold mornings. Similarly, plants exhale water vapor through a process called transpiration, where gases like oxygen are also released. On hot days, a football pitch can lose water equivalent to thousands of liters. Plants have stomata, tiny holes in leaves, that open and close to regulate water loss.

What can you observe when you exhale on a cold morning?
