Document Summary

Plant evolution has given rise to two methods of reproduction (18. 1) Plants are extremely varied in their appearance and strategies used to attract pollinators. Because plants cannot move, they have different reproductive strategies that allow their species to be successful. For most plants, sexual reproduction is more common. Nearly all plant species have the ability to reproduce without another if the need arises. Many plants can reproduce asexually when necessary (18. 2) The process of asexual reproduction in plants is simple. It always involves the growth of new individual plants directly from the tissue of an established plant via normal mitosis. The new individual is genetically identical to the individual from which it was produced. No energy is wasted by producing tissues used exclusively for sexual reproduction, such as flowers, pollen, and fruit. Asexual reproduction dramatically increases the rate at which new individuals can be produced, enhancing an individual"s fitness: preserves winning allele combinations.
