1. **Understanding Plant Growth Phases**:
- Plants undergo three main growth phases: the meristematic phase, the elongation phase, and the maturation phase.
- In the meristematic phase, cells are actively dividing.

2. **Transition to Elongation Phase**:
- After the meristematic phase, cells enter the elongation phase. This is characterized by the cells no longer dividing but instead increasing in size.
