- Meristems are groups of immature cells that are still capable of dividing. There are four types
- 1) Apical meristems- located at the tips (apex) of roots and shoots
- 2) Lateral bud meristems- Found in buds
- 4) Lateral meristems- responsible for roots and shoots getting wider.
- 5) Intercalary meristems- located between nodes
- 4) Lateral meristems- responsible for roots and shoots getting wider.

- Cytokinins- Prevent senescing (aging and dying)
- Auxins- The extent to which cells elongate is proportional to the concentration of auxins. Auxin first increases the stretchiness of the cell wall (by actively transporting H+ ions. The low pH provides optimum conditions for a wall loosening enzyme to work.
