Document Summary
Many plants can also reproduce asexually producing new individuals without the formation and fusion of gametes. Sexual reproduction relies on spores and seeds. Asexually produced plants disperse with and without seeds: Some species of flowering plants are able to use seeds to disperse asexually formed individuals. Seeds can develop even in the absence of fertilization a process called apomixis. Most plants that reproduce aseually do so by growing to a new location and only then producing a new plant. Vegetative reproduction also occurs in woody plants. Plants can reproduce vegetatively because of the way they build their bodies. Growth and development occurs throughout a plants life and this characteristic that allows plants to produce new upright individuals from roots or horizontal stems. In tropical forests, vines weave their way upward through the branches of trees. Plant shoots are modular, meaning that they are formed of repeating units.
