There are present two types of tissues in the plants :
Meristematic Tissues : Meristematic tissues have undifferentiated cells which form the building blocks of the specialized plant structures.
Permanent Tissues : The permanent tissues in a plant are those tissues that contain non dividing cells. The cells are also modified to perform specific functions in plants. Xylem is the part of complex permanent tissue. These tissues perform the activity of conduction of water and minerals in different parts of the body.
Xylem, or wood, as it is often called, is a complex tissue. The cells are thick-walled, tubular and often dead. This tissue has four types of cells : tracheids, vessels, xylem parenchyma and xylem fibres. Of these only tracheids and vessels transport sap.
