What to Focus On

  • Root develops from the radicle of the embryo.
  • Positively geotropic and negatively phototropic.
  • Four regions: meristematic, elongation, root hair, and maturation zones.
  • Tap roots in dicots; fibrous roots in monocots.
  • Adventitious roots arise from non-radicle parts.
  • Fibrous roots provide good anchorage in shallow soils.
  • Roots modified for storage, respiration, support, climbing, and nitrogen fixation.
  • Nodules in legumes help in nitrogen fixation.
  • Pneumatophores help in gaseous exchange in waterlogged soils.

Common Mistakes to Avoid

All roots grow underground and all stems grow above ground.

Tap roots are only in dicots and fibrous roots only in monocots.

All leaves perform photosynthesis, so any green structure is a leaf.

Memory Tips
