- Plant Cloning
- Natural
- Vegetative Propagation
- Production of clones from non-reproductive tissue
- Methods
- 3. Suckers
- Shoots grow from sucker buds on roots of parent plant
- Elm Trees
- Shoots grow from sucker buds on roots of parent plant
- 2. Runners
- New shoots also from end of runner
- Same as 1. But grow above ground
- Strawberries
- 4. Tubers
- Underground plant structures
- Act like food storage
- Covered in 'eye' that sprout to form new plants
- Potatoes
- 5. Bulbs
- New bulbs form from original
- Onions
- 1. Rhizomes
- Stem structures
- Grow horizontally underground
- Bamboo
- 3. Suckers
- Vegetative Propagation
- Artificial
- Tissue Culture
- Against tissue culture
- 2. Undesirable genetic characteristic passed on
- 4. No genetic variation
- 1. Production costs are high
- 3. Contamination by microorganisms can be disastrous
- Method
- 1. Cells are taken from the stem or root
- 3. Placed on culture medium
- 4. When cells have divided and grown into a small plant, it is replanted in soil
- 2. Sterilised
- Kills any micro organisms that may compete
- Decreases growth rate
- For tissue culture
- 3. Less space requires
- 2. Any season
- 4. Produces lots of plants quickly
- 1. Desirable genetic characteristic are passed on
- Against tissue culture
- Tissue Culture
- QUESTIONS
- 1. What is vegetative propagation?
- 2. A scientist wants to produce a whole plant from a genetically engineered plant stem cell
- Describe how she could achieve this
- Natural
