**[Questions]** What is vegetative propagation? Asexual reproduction in plants whereby there is one parent and offspring are clones. Name two parts of the plant that may be specially modified for this purpose. Stem/root/leaf/bud Give an example of a modified stem as well as a plant that exhibits this. Runners e.g strawberry  Or Stem tubers e.g potato Give an example of a modified root as well as a plant that exhibits this. A root tuber. E.g.Dahlia Give an example of a modified leaf as well as a plant that exhibits this. Plantlets. E.g. lily Give an example of a modified bud as well as a plant that exhibits this. Modified bulb. E.g. onion Give two advantages of sexual reproduction in the flowering plant. - More resistant to disease - Dispersal reduces competition Give two advantages of asexual reproduction in the flowering plant. - No waste - Rapid growth Give two disadvantages of sexual reproduction in the flowering plant. - Slow growth of young plants to maturity - Wasteful Give two disadvantages of asexual reproduction in the flowering plant. - No variation - If one plant is susceptible to disease, all of the plants are susceptible to the disease Name two methods of artificial propagation. Cutting/layeing/grafting/micropropagation What is micropropagation? Cells are removed from the plant and grown as a tissue culture in a special medium
