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!
- Take small sample of tissue from parent plant
- Grow in sterile agar with nutrients and hormones
- Cells divide and form new plants
- All plants are genetically identical clones
Uses: Rapid production of identical plants; preserving rare species
