Xylem tissues are those tissues that provide a passage for the upward movement of water and dissolved materials.
Permanent tissues are made up of cells that have lost their ability to divide.
There are the following characteristics of meristematic tissue are:- Cells are small. Cells are usually cubical. The cell wall is thin. Nuclei are large. Vacuoles are almost absent.
The cells can multiply to produce new cells found at all growing points of a plant.
