Presentation Transcript

  1. Clones Genes, cells or whole organisms that carry identical genetic material because they are derived from the same original DNA.

  2. Asexual reproduction.

  3. Vegetative propagation Production of structures that can grow into a new organism, genetically identical to the original organism

  4. Micropropagation by tissue culture • Remove small section of the shoot tip of the plant to be cloned. This small section is called the explant • Place the explant on nutrient agar • On the agar the cells divide to form a mass on undifferentiated cells called a callus • The callus can be subculturedonto more agar plates • Plant hormones are added to make the callus develop shoots • After a few weeks different hormones are added to cause root growth • The plantlets are then transferred to soil in a greenhouse and slowly acclimatised
