Reproduction


The process by which organisms
       produce offspring
Reproduction

           The Essential Question!



   How are sexual and asexual
    reproduction the same and how are
    they different?
Types of Reproduction
   Sexual: Two parents have offspring;
    offspring share traits from both
    parents.




   Asexual: One parent has offspring;
    offspring are genetically identical to
    parent.
Sexual Reproduction
   Animals: Female parent produces an
    ovum, male parent produces a sperm. Both
    combine to produce an offspring, with
    genetic material from each parent.

   Plants: Female part of the plant produces
    an ovum, male part of the plant produces
    pollen. Both combine to produce an
    offspring, with genetic material from each
    parent.
Asexual Reproduction

 Binary Fission: The process by which
  the organism splits into two.
 Most bacteria and protozoa reproduce
  by binary fission.
Asexual Reproduction

 Budding: an offspring grows out of
  the body of the parent.
 Hydra and sponges reproduce by
  budding.
Vegetative Propagation

 The production of a new organism
  from a portion of another organism
 Plants can reproduce by vegetative
  propagation
Regeneration
 The re-growth of a lost or damaged
  part of an organism
 Starfish can regenerate an arm

 Planaria can regenerate into two
  organisms
Reproduction

  again?
