Topics in Plant Growth and Development

1

Growth and Its Characteristics

  • Growth is an irreversible permanent increase in size of an organ, its parts, or individual cells
  • Plant growth is indeterminate - plants can grow throughout their life due to meristems
  • Growth occurs due to meristematic activity at root apex, shoot apex, and lateral meristems
2

Phases of Growth and Growth Rates

  • Three phases of growth: Meristematic, Elongation, and Maturation
  • Meristematic phase: Constantly dividing cells with large nuclei, thin cellulosic walls
  • Elongation phase: Increased vacuolation, cell enlargement, new cell wall deposition
3

Conditions for Growth and Differentiation

  • Essential conditions: Water, oxygen, nutrients, optimum temperature
  • Water provides medium for enzymatic activities and helps in cell enlargement
  • Turgidity helps in extension growth
4

Development and Plasticity

  • Development = Growth + Differentiation
  • Development includes all changes from seed germination to senescence
  • Plasticity: Ability to form different structures in response to environment or life phases
