Functions of Meristematic Tissue:
1. Meristems are actively dividing tissues of the plant.
2. They are responsible for primary (elongation) and secondary (thickness) growth of the plant.
3. All new organs and their growth occur by the division of meristematic tissue.
4. Secondary tissues such as, wood, cork are also formed due to activity of meristematic tissue.
Types of meristematic tissue on the basis of function:
i. Protoderm
ii. Procambium
iii. Ground meristem
Protoderm:
Function:
Protection from mechanical injury
It gives rise to epidermis layer.
It is the outermost meristematic tissue
Procambium:
Function:
Transport of water and nutrition
It gives rise to vascular tissue (xylem and phloem)
It is the innermost meristematic tissue
Ground meristem:
Function:
It gives rise to cortex, endodermis, pericycle and pith in dicot and hypodermis, ground tissue in monocot.
