Question 3

Stolon, offset and rhizome are different forms of stem modifications. How can these modified forms of stem be distinguished from each other?

Answer

 

Stolon

Offsets

Rhizome

  • Stolon is a type of creepers (weak stemmed plants).
  • These are the special types of runners which initially grow in upward direction like ordinary branches and then bent down to develop new plants.  
  • Example: Strawberry (Fragaria vesica)
  • Offsets is a type of creepers (weak stemmed plants).
  • Offsets are one internode condensed runners usually found in rosette plants.
  • Each offset produces at its apex a tuft of leaves above and a cluster of roots below.
  • Example: Eichhornia (water hyacinth)
  • Underground stems growing parallel or below to soil surface is called Rhizome.
  • Most of the rhizomes are fleshy and store reserve food materials.
  • They are differentiated into nodes and internodes.
  • Nodes bear brown scale leaves which protects axillary buds.
  • It helps in vegetative propagation.
  • Example: Rhizome of Zingiber officinale (ginger)
