Sexual reproduction in plants occurs when a detached reproductive cell unites with another reproductive cell. Unlike animals, plants do not have to have separate male and female sexes, in many plants both sexes are located on the same species. In asexual reproduction, the cell, tissue, or organ develops directly into a new organism. Sexual reproduction allows combinations of different genetic material to be introduced into a new individual this is the method by which humans reproduce and provides for genetic rearrangement and assortment. In asexual reproduction an exact copy is made from the mother cell, therefore, the genetic material remains the same. Vascular plants are more complicated than non-vascular plants.
What types of plants reproduce sexually? – mac-moto.com
In the plants included in this article—bryophytes mosses, hornworts, and liverworts and tracheophytes vascular plants —sexual reproduction is of the oogamous type, or a modification thereof, in which the sex cells, or gametes, are of two types, a larger nonmotile egg and a smaller motile sperm. Daffodils are a plant that can reproduce both ways; asexually from their bulb and sexually through seed production. 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. Animals that reproduce asexually include planarians, many annelid worms including polychaetes and some oligochaetes, turbellarians and sea stars. Many fungi and plants reproduce asexually. Some plants have specialized structures for reproduction via fragmentation, such as gemmae in liverworts. Plant reproduction is the production of new offspring in plants, which can be accomplished by sexual or asexual reproduction.
There are several different methods and processes involved in the sexual reproduction of plants. Many of the structures associated with sexual reproduction in plants are valuable commodities for humans think fruits, berries, and vegetables. In angiosperms, pollination is defined as the placement or transfer of pollen from the anther to the stigma of the same flower or another flower.
Plant reproduction is the production of new offspring in plants, which can be accomplished by sexual or asexual reproduction. Sexual reproduction produces offspring by the fusion of gametes , resulting in offspring genetically different from the parent or parents. Asexual reproduction produces new individuals without the fusion of gametes, genetically identical to the parent plants and each other, except when mutations occur. Asexual reproduction does not involve the production and fusion of male and female gametes.
