Reproduction Asexual vs. Sexual

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?

  • 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?

  • 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?

  • 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

  • Asexual

  • Cell splits and replicated DNA goes with each part

  • Bacteria

  • + Fast and easy

  • - Everybody has the same DNA

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

Fragmentation/ regeneration


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?

  • 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

  • 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.
