Summary Introduction
Introduction:
Water and minerals obtained from the soil together called xylem sap, pass through the xylem, and the cells that transmit water inside a plant. Through transpiration, the plant essentially extracts a sap column through the roots from the soil, up tubes that composed of xylem dead cells in stem, and then into the leaves.
