Asexual reproduction methods

Archived from the original on 23 September Examples include the prostrate aerial stems of strawberries, the bulbs of tulips, the tubers of potatoes, the shoots of dandelions, and the keikis of orchids. Five Types of Asexual Reproduction. Spores are structures naturally grown as part of an organism's life cycle and designed for separation from the organism and dispersal via a medium such as air or water. Examples are parthenogenesis and apomixis. Some cells split via budding for example baker's yeast , resulting in a "mother" and "daughter" cell.

Asexual reproduction

By asexual reproduction, an organism creates a genetically similar or identical copy of itself. For instance, most plants are capable of vegetative reproduction —reproduction without seeds or spores—but can also reproduce sexually. Scientists have speculated about the possibility of creating life non-reproductively in the laboratory. When food sources have been depleted, the climate becomes hostile, or individual survival is jeopardized by some other adverse change in living conditions, these organisms switch to sexual forms of reproduction.

General features of asexual systems

Molecular evidence strongly suggests that several species of the stick insect genus Timema have used only asexual parthenogenetic reproduction for millions of years, the longest period known for any insect.

Retrieved 4 August Examples include the prostrate aerial stems of strawberries, the bulbs of tulips, the tubers of potatoes, the shoots of dandelions, and the keikis of orchids. Many algae similarly switch between sexual and asexual reproduction. Vegetative propagation is a type of asexual reproduction found in plants where new individuals are formed without the production of seeds or spores by meiosis or syngamy. Parthenogenesis occurs naturally in many plants, invertebrates e. Since sexual reproduction is often more narrowly defined as the fusion of gametes fertilization , spore formation in plant sporophytes and algae might be considered a form of asexual reproduction agamogenesis despite being the result of meiosis and undergoing a reduction in ploidy. Bdelloid rotifers reproduce exclusively asexually, and all individuals in the class Bdelloidea are females.
