Asexual and sexual reproduction

Cards (14)

  • Artificial vegetative propagation is a process where asexual methods are used with the help of humans, also known as artificial propagation.
  • Artificial propagation is often faster than growing plants from seeds.
  • Farmers propagate plants by using a piece of parent plant material.
  • If a portion of a plant's stem is cut and left in water, new roots or shoots may grow, resulting in the formation of an entirely new plant.
  • Each new plant is genetically identical to its parent and is said to be a clone.
  • The widely used methods of artificial vegetative propagation include cuttings, budding, grafting, and air layering.
    • Cutting - Leaves, stems, or roots are cut from one plant, planted in soil, and used to grow new plants/ornamental trees and shrubs (grapes, apples)
    • Budding and grafting - Small stems from one plant are attached to the larger stems or roots of another plant./Some fruits (oranges) and nut trees.
    • Tissue culture - Laboratory technique in which pieces of tissue from one plant are placed on a sterile medium and used to grow new plants/orchids,potatoes,and ornamental plants
  • Vegetative propagation allows farmers to produce large numbers of clones quickly and cheaply.
  • most plants reproduce asexually by using their vegetative part such as stems, roots, and leaves
  • Asexual reproduction can occur either naturally or artificially with the aid of humans
  • plants can reproduce through their vegetative parts or specialized reproductive structures.
  • This type of reproduction is called natural vegetative propagation.
  • the vegetative propagatio. In this process, new plants are produced naturally from the nodes or eyes of potatoes, cloves of garlic, or runners of strawberry plants.
  • most plants structures involved in vegetative propagantion are modified stems such as runners, rhizomes, corms, tubers, and bulbs
