What to Focus On

  • Growth is quantitative and irreversible.
  • Differentiation is qualitative specialization.
  • Plants show open form of growth because meristems keep producing new cells.
  • Growth may be measured by length, diameter, volume, area, weight, or cell number.
  • A horizontal microscope measures growth by the movement needed to refocus the tip.
  • An auxanometer measures elongation of shoots.
  • Plant growth usually follows an S-shaped sigmoid curve.
  • The three phases are lag, logarithmic, and stationary.
  • Exponential growth follows the compound interest law.

Common Mistakes to Avoid

Growth and development mean the same thing.

Differentiation means cells increase in size or number.

Open form of growth means growth happens only for a short time and then stops.
