  1. The ability of a plant cell to give rise to a whole plant is called totipotency.
  2. The culture of a cell or a tissue in a suitable medium to produce new plants is called tissue culture. This process is discovered by G. Haberlandt in 1902.
  3. By tissue culture techniques new plants can be obtained from single cells or a tissue or a bud or other organs of the plant.
  4. The portion of the plant that is used in tissue culture technique is called as explant.
  5. The techniques require maintenance of sterile conditions in the medium.
  6. The medium should contain sugars, minerals and one or more growth regulators and are kept free form bacteria and fungi. Explant should be sterilised.
  7. The explant divides to give rise to an unorganised mass of tissue called callus.
