Types of Reproduction
  • Asexual
  • Sexual
2
Purpose of Reproduction
  • To make sure a species can continue.
    • Definition:  Reproduction is the process by which an organism produces others of its same kind.

3
Asexual Reproduction
  • A new organism (sometimes more than one) is produced from one organism.
  • The offspring will have hereditary material uniform with the hereditary material of the parent organism. This means they will be genetically alike.
4
Types of Asexual Reproduction
  • Budding
  • Regeneration
  • Fission (Binary fission)
5
Budding
  • Process by which a new, duplicate plant or animal begins to form at the side of the parent and enlarges until an individual is created.
  • Very common in plants;

Sexual Reproduction
  • Requires two sex cells – egg and sperm
  • The egg and sperm join to form an entirely new organism
    • Different from the parent organism

IMPORTANT!
  • Asexual reproduction results in offspring that are genetically identical to the parent organism
  • Sexual reproduction results in offspring that are genetically different from the parent organisms
