Plant tissue culture or Micro-propagation is
1. Used to produce clones of a plant
2. Performed in the wild
3. Used to conserve rare or endangered plant species

The correct answer is 1 and 3.

Important Points

• It is performed under sterile conditions in a nutrient culture medium (laboratory conditions). So, statement 2 is NOT correct.
• Plant tissue culture relies on the fact that many plant cells have the ability to regenerate a whole plant.
• Plant tissue culture is used widely in the plant sciences, forestry, and in horticulture.
• Applications include:
  • To quickly produce mature plants.
  • The production of multiples of plants in the absence of seeds or necessary pollinators to produce seeds.
  • The regeneration of whole plants from plant cells that have been genetically modified.
  • The production of plants from seeds that otherwise have very low chances of germinating and growing, i.e.: orchids and Nepenthes.
  • To clean particular plants of viral and other infections and to quickly multiply these plants as 'cleaned stock' for horticulture and agriculture.
  • The commercial production of plants used as potting, landscape, and florist subjects, which uses meristem and shoot culture to produce large numbers of identical individuals.
  • To conserve rare or endangered plant species.
  • To cross-pollinate distantly related species.
