Study Notes
Vegetative Propagation
- Asexual reproduction method in plants with one parent, resulting in offspring that are clones.
- Involves modification of certain plant parts for propagation purposes.
Modified Plant Parts for Propagation
- Stem: Runners (e.g., strawberry) and Stem tubers (e.g., potato).
- Root: Root tuber (e.g., Dahlia).
- Leaf: Plantlets (e.g., lily).
- Bud: Modified bulb (e.g., onion).
Advantages of Sexual Reproduction in Flowering Plants
- Enhances resistance to diseases through genetic diversity.
- Allows dispersal of seeds, reducing competition for resources.
Advantages of Asexual Reproduction in Flowering Plants
- Minimizes waste as no energy is spent on producing seeds.
- Enables rapid growth and establishment of new plants.
Disadvantages of Sexual Reproduction in Flowering Plants
- Young plants take considerable time to reach maturity.
- Can be wasteful due to energy expended on pollination and seed production.
Disadvantages of Asexual Reproduction in Flowering Plants
- Lacks genetic variation, making all clones susceptible to the same diseases.
- A single disease outbreak can wipe out entire populations of cloned plants.
Methods of Artificial Propagation
- Various techniques include cutting, layering, grafting, and micropropagation.
Micropropagation
- Involves removing cells from a plant and culturing them in a special medium to grow new plants.
