Title: Reproduction


1
Reproduction
  • By Darcy Davis, Kara Kime, Katherine Shockey,
    Foster Smith

2
Types of Reproduction
  • Sexual- involves the fusion of two special cells
    called gametes, sperm and eggs, one from each
    type of gender.
  • Asexual- reproducing without the interaction of
    two sexes or genders.

3
Examples
  • Asexual- budding, sponges, starfish, bacteria,
    starfish.
  • Sexual- humans, most mammals except for platypi.

4
Differences
  • Sexual- 2 parents one male, one female,
    genetically different, new characteristics
    introduced, cells produced by meiosis.
  • Asexual- 1 parent, genetically identical, no new
    characteristics introduced, cells produced by
    mitosis.

5
Similarities
  • Both types form an offspring.
  • Both pass traits when they reproduce.
  • Both are ways to produce new individuals.

6
Mitosis and Meiosis
  • Mitosis- Asexual reproduction, a cell is formed
    that is identical to the first cell.
  • Meiosis- Sexual reproduction, sex cells are
    formed with half the chromosomes of a normal
    cell.

7
Why is reproduction necessary?
  • New individuals can be produced.
  • New characteristics are introduced into the
    genetic community.
  • Species will continue its existence.
  • New characteristics are introduced so that they
    can hopefully improve an organisms chance for
    survival, in sexual reproduction.
