Cloning Plants

Definition

Cloning = producing genetically identical organisms.

• A clone has the same DNA and characteristics as the original.

• Advantage: predictable traits (e.g., flower color).

Methods of Plant Cloning

1. Taking Cuttings

• Small piece of plant is removed.

• End is dipped in rooting powder (contains plant hormones).

• Hormones stimulate root growth.

• Produces a genetically identical clone.

• Suitable for producing a few clones.

2. Tissue Culture (Higher Tier / Large Scale)

• Plant divided into hundreds of tiny pieces (each with a few cells).

• Pieces incubated with plant hormones → stimulate growth into full plants.

• Must be sterile to prevent contamination by bacteria or fungi.

• Produces thousands of clones quickly and cheaply.

• Used in commercial nurseries and to preserve rare plant species.

✅ Key Takeaways

• Cloning produces genetically identical plants.

• Cuttings → simple, small-scale cloning.

• Tissue culture → large-scale cloning, faster, cost-effective.

• Ensures desired traits (e.g., flower color) are maintained.

• Sterile conditions are critical for tissue culture success.
