Tissue - a group of cells that perform essentially the same function, commonly in a similar structure, and organized into a functional and structural unit
Meristematic - perpetually young tissues primarily concerned with formation of new cells
Apical Meristem - Located at the main and lateral shoots and roots
Root Apical Meristem
Shoot Apical Meristem
Lateral Meristem - Arranged parallel to the sides of the organ in which it occurs
Vascular cambium
Cork cambium
Intercalary Meristem - actively growing region away from the apex
meristem is inserted between more or less differentiated tissue regions
When an initial divides, one of the daughter cells remains as an initial to maintain the meristem.
Derivatives or meristematic derivatives (specialized meristematic cells)
