purpose of reproduction
Purpose of Reproduction
  • To make sure a species can continue.
    • Definition: Reproduction is the process by which an organism produces offspring of the same kind.
  • There are 2 types of reproduction:
    • Asexual
    • Sexual
asexual reproduction what
Asexual reproduction- What?
  • A form of reproduction which does not involve fertilization (does not depend on male and female parts)
  • A new organism (sometimes more than one) is produced from only one organism.
    • Asexual reproduction = one parent.
  • Produces offspring that are genetically identical to their parent
asexual reproduction who
Asexual Reproduction- Who?
  • The primary form of reproduction for single-celled organisms (ex: bacteria)
  • Many plants and fungi reproduce asexually as well.
  • Some animals reproduce asexually as well (sponges, hydras)
asexual reproduction types
Asexual Reproduction- Types?
  • There are several types of asexual reproduction:
    • Budding
    • Binary Fission
    • Regeneration
  • Asexual
  • Offspring grows out of parent
  • Yeast, hydras
  • + Fast, somewhat easy
  • - Same DNA

binary fission
Binary Fission
  • Asexual
  • Cell splits and replicated DNA goes with each part
  • Bacteria
  • + Fast and easy
  • - Everybody has the same DNA

fragmentation regeneration
Fragmentation/ regeneration
  • Asexual
  • The ability to restore lost or damaged tissues, organs or limbs.
  • It is a common feature in invertebrates, like worms and starfish.
  • + Easy
  • - Parent broken, same DNA

sexual reproduction what
Sexual Reproduction- What?
  • Requires BOTH male (sperm) and female (ovum- egg) gametes (sex cells)
  • The ovum and sperm join to form an entirely new organism that is genetically different from both parents
    • This results in increasing genetic diversity of the offspring.
sexual reproduction who
Sexual Reproduction: Who?
  • Primary method of reproduction for the vast majority of visible organisms, including almost all animals and some plants.
  • 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
pollination sexual reproduction in flowering plants
Pollination- sexual reproduction in flowering plants
  • Sexual
  • Pollen is delivered to female part of plant
  • Occurs in flowering plants
  • + Plants don’t have to move, mixes DNA
  • - Need external source for pollination to take place; wind, bee, bat, butterfly etc.
