-used for storage
Sclerenchyma
Support cells
Determinate growth
destined to form a terminal structure.
-leaf and flower
-programmed, ends with differentiation into non dividing cell types
Indeterminate growth
-in meristems
-undifferentiated cells persist while new roots and shoots grow
-contain potential to develop into all root and shoot structures
