Class 10 Biology How Do Organisms Reproduce Natural Vegetative propagation

Natural Vegetative propagation

By roots

  • Buds develop in thick, fleshy roots which later, when put into soil develop into new plants
  • Guava, sweet potato, dahlia


By stems


  • Stems that grow horizontally above ground
  • Examples: Grass, strawberry


Underground stems

  • Potato’s tubers which are fleshy are underground storage structures. Buds give rise to aerial shoots under favorable conditions.
  • Ginger’s rhizomes are modified stems found underground. Buds appear at their nodes which can give rise to new plants.
  • Onion’s bulbs are short underground vertical shoots with thickened leaves. Roots emerge from underside of the stem.

By leaves

  • Buds are formed along leaf margins which later give rise to a new plant
  • Examples: Bryophyllum
