Cell growth and cell division
WebCell cycle checkpoints. A checkpoint is a stage in the eukaryotic cell cycle at which the cell examines internal and external cues and "decides" whether or not to move forward with division. There are a number of checkpoints, but the three most important ones are: start subscript, 1, end subscript. start subscript, 1, end subscript. /S transition.

WebCell division alone does not constitute growth but rather increases the potential for growth by increasing the number of cells that can subsequently undergo expansion. Growth itself relies on the process of cell expansion and, in plants, this mechanism is highly dependent on the mechanical properties of the cell wall.
