xylem

Xylem:Xylem is a type of tissue in plants that transports water and nutrients from the roots to the leaves. Xylem tissue is made up of cells that are arranged in a series of tubes. The cells are connected to each other by specialised structures called pit membranes.Water and nutrients are transported through the xylem tissue by two processes: osmosis and transpiration. Osmosis is the movement of water molecules from an area of high concentration to an area of low concentration. Transpiration is the evaporation of water from the leaves, which creates a negative pressure gradient that pulls water up through the xylem tissue.
