  • Some Plants Grow Side Branches that Contain Plantlets which Specialise into Forming Root Hair Cells when they Touch the Ground
  • These Plantlets will Grow Roots and Plants will Grow, Allowing Asexual Reproduction

  • Tissue Samples are Placed in Agar Growth Medium Containing Nutrients and Auxins
  • Samples Develop into Tiny Plantlets
  • Plantlets are Planted into Compost
