Different circumstances require either of these these seeds, and pollen is required for this tiny black seeds are dry and ready for dispersal. What an interesting world we live in! Daffodil reproduction through the asexual production of bulbs provides a more efficient and faster way to produce offspring, although the new bulbs remain genetically identical to the mother bulb. Strawberries are similar in that they can reproduce sexually through seed production, or asexually with runners that spread through the ground and create daughter plants from the parent. In fission reproduction, a single cell is divided into two equal halves. After maturation, it detaches from the main body and becomes a new independent individual. How do you calculate working capital for a construction company? If you contribute half of your genes and your partner contributes half of his or her genes, the genetic makeup of the new individual is far more diverse than if you were to produce a genetically identical offspring through asexual reproduction.

Three methods of plant asexual reproduction are: Bulbs - underground food storage organs with fleshy leaves that store food and can grow and develop into new plants, eg onions and garlic.. For example, if the environment is very stable during one part of the year with plentiful food, water, and other resources, an organism might want to reproduce asexually to create a large, uniform population.
