What to Focus On

  • Growth is irreversible and permanent.
  • Plants show indeterminate growth because meristems remain active.
  • Growth is measurable by weight, length, area, volume, and cell number.
  • Differentiation leads to specialised cells and tissues.
  • Tracheary elements lose protoplasm and form thick secondary walls.
  • Dedifferentiation restores the ability to divide.
  • Development is the sum of growth and differentiation.
  • Plant development begins with seed germination and ends in senescence.
  • Plasticity allows different forms to develop under different conditions.

Common Mistakes to Avoid

Growth is the same as increase in size only, so any swelling or change in shape must be growth.

Plants stop growing after reaching maturity, just like many animals do.

Root apical meristem, shoot apical meristem, and vascular cambium all do the same kind of growth in the same plants at the same stage.
