What is the definition of transpiration?

The definition of transpiration is the physiological process by which plants absorb water from the soil through their roots, transport it through their vascular system, and release it into the atmosphere as water vapor through small pores called stomata. This process is vital for maintaining the plant’s internal water balance, cooling, and nutrient uptake. Transpiration also plays a role in the water cycle by contributing to atmospheric moisture and influencing weather patterns.
