transpiratii

Transpiration is the process by which plants release water vapor into the atmosphere. It occurs through small openings on the surface of leaves called stomata. The primary function of transpiration is to regulate the plant's internal water balance and facilitate the transport of water and nutrients throughout the plant. This process is driven by the evaporation of water from the leaf surfaces, which creates a negative pressure (tension) that pulls water up from the roots through the xylem vessels. Transpiration also plays a crucial role in cooling the plant, as the evaporation of water requires energy, which is taken from the plant's surroundings, thereby lowering its temperature. The rate of transpiration is influenced by various factors, including light intensity, temperature, humidity, and wind speed. Transpiration is an essential process for the survival and growth of plants, as it ensures the continuous supply of water and nutrients to all parts of the plant.
