Plant Cloning — Tissue Culture

The Photocopy Machine

Cloning is like making photocopies of an organism. All the copies have IDENTICAL DNA to the original. Plant cuttings are the simplest clones. Dolly the sheep was the first mammal cloned from an adult cell!

  1. Take small sample of tissue from parent plant
  2. Grow in sterile agar with nutrients and hormones
  3. Cells divide and form new plants
  4. All plants are genetically identical clones

Uses: Rapid production of identical plants; preserving rare species

Quick Recall Flashcards

What is a clone?
A genetically identical copy of an organism. Clones have exactly the same DNA as their parent. Cloning occurs naturally (e.g. identical twins, bacterial reproduction) and can be done artificially in plants and animals.
What was significant about Dolly the sheep?
Dolly (born 1996) was the first mammal cloned from an adult (somatic) cell. This proved that a specialised adult cell could be reprogrammed to create a whole organism — previously scientists thought adult cells had permanently 'switched off' the genes not needed for their function.
