What is the difference between viviparous and ovoviviparous reproduction?

Viviparous animals give birth to live young that develop inside the mother's body. Ovoviviparous animals give birth to live young that hatch from eggs that remain in the mother's body until they are ready.

Study Notes

Asexual Reproduction

  • Offspring comes from a single parent
  • Exact copy of parent's genes
  • Does not involve the union of gametes (sperm and egg)
  • Offspring is similar or identical to parent
  • Very common in plants; less common in animals

Budding (Blastogenesis)

  • New organism develops from an outgrowth or bud
  • Cell division at specific site
  • Bud forms a small group of cells on the side of parent

Kingdom Fungi

  • Heterotrophic: obtain nourishment by absorbing small food molecules

Phylum Zygomycota

  • Example: Rhizopus (common bread mold)
  • Asexual reproduction by releasing spores from sporangia

Phylum Basidiomycota

  • Example: Mushrooms
  • Important group; many are edible

Phylum Ascomycota

  • Not further detailed in the image
