The meristematic tissues that take up a specific role lose the ability to divide. This process of taking up a permanent shape, size and a function is calledcellular differentiation. Cells of meristematic tissue differentiate to form different types of permanent tissue. There are 3 types of permanent tissues:
1. simple permanent tissues
2. complex permanent tissues
3. special or secretory tissues (glandular).
