Xylem and Phloem - Part 2 - Transpiration - Transport in Plants

The video explains how water and minerals move through plants via transpiration and the xylem. Transpiration involves water evaporation from leaves, creating a suction that pulls water up from the roots. Water moves through xylem vessels, supporting photosynthesis and cell turgidity. The transpiration stream also transports minerals. Factors like temperature, humidity, and leaf structure affect transpiration rates. Guard cells regulate stomata opening, controlling water loss based on water potential changes during day and night.
