||The skin is formed by one layer of cells with dense membranes (present only in young shoots).
The cork consists of several layers of dead, air-filled cells. Lentils are formed by large cells of the main tissue with large intercellular spaces
|Protection of deeper cells from damage, excessive evaporation of moisture, penetration of pathogens. Gas exchange is carried out through the lentils
|The inner part of the bark. Consists of sieve tubes, companion cells, storage cells and dead cells of mechanical tissue, which give strength to the bast
||Conducting organic matter from leaves to root, storing nutrients
||Formed by one layer of living narrow long cells with thin membranes
||Cell division and stem growth in thickness
|It is formed by cells of various sizes and shapes: the vessels of the conductive tissue consist of dead cells with thickened walls. Wood fibers are made up of thick-walled cells
||Conduction of water and minerals, support function
||Consists of large, thin-walled, loosely adjacent cells
