Tip growth

Tip growth is an extreme form of polarised growth of living cells that results in an elongated cylindrical cell morphology with a rounded tip at which the growth activity takes place. Tip growth occurs in algae (e.g., Acetabularia acetabulum), fungi (hyphae) and plants (e.g. root hairs and pollen tubes).
