vízelvitel

Vízelvitel, also known as transpiration, is a biological process by which water is carried through plants from the ground to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. This process is crucial for the plant's survival and growth, as it helps to cool the plant, transport nutrients, and maintain the plant's structure. The water is transported through the plant's vascular system, which includes xylem and phloem tissues. The xylem carries water and minerals from the roots to the leaves, while the phloem transports sugars and other organic compounds produced by photosynthesis. Transpiration is driven by the evaporation of water from the leaf surfaces, which creates a negative pressure that pulls water up from the roots. The rate of transpiration can be influenced by various factors, including temperature, humidity, wind speed, and the plant's internal water status. In some plants, transpiration can also help to distribute water evenly throughout the plant, ensuring that all parts receive adequate moisture.
