Study Notes

Asexual Reproduction

  • Involves one parent
  • No sex cells are produced
  • Offspring are produced by cell division
  • Offspring are identical to the parent, having the same DNA
  • Several types of asexual reproduction exist in plants and animals

Types of Asexual Reproduction

  • Binary Fission

    • Organism divides in half
    • 2 identical daughter cells are produced
    • Daughter cells are half the parent's size
    • Daughter cells grow and then divide too
    • Occurs in bacteria
  • Budding

    • A small bud grows out of the parent cell
    • Two different sized cells are made, with identical DNA
    • The bud breaks off and grows
    • Occurs in yeast and hydra
  • Regeneration

    • Involves repairing or growing lost body parts
    • Leftover cells divide to make more cells
    • Occurs in lobsters, starfish, and lizards

Sexual Reproduction

  • Involves 2 parents
  • Sex cells (sperm and egg) are produced
  • Sperm and egg join during fertilization
  • Offspring look different from the parents, having mixed DNA
  • Examples include humans, some plants, mammals, fish, reptiles, etc.

Fertilization

  • Part of the process of sexual reproduction
  • A male reproductive cell and a female reproductive cell combine
  • Forms a new cell that can develop into a new organism
