Reproduction Of Animals

• Asexual reproduction


  Formation of new individuals from the cells of a single parent. The resulting offspring is identical to the parent and without the need for a mate.
• Types of asexual reproduction


  • Fragmentation
  • Binary fission
  • Budding
  • Parthenogenesis
• Fragmentation


  Pieces of the parent breaks off and develops into a new animal
• Binary fission


  Process in which an organism divides into two and grow into a new organism
• Budding


  Process outgrowth or callus projecting from the parent and eventually buds off
• Parthenogenesis


  Mechanism of asexual reproduction in which female offspring develops from unfertilized eggs
• A plant part such as stems, leaves, roots, or turions are used to produce new plants.
• Hydra (Hydra Oligactis) reproduces asexually
• Types of asexual reproduction in Hydra


  • Fragmentation
  • Binary fission
  • Budding
  • Parthenogenesis
• Types of asexual reproduction in Amoeba (Amoeba proteus)


  • Fragmentation
  • Binary fission
  • Budding
  • Parthenogenesis
• Types of asexual reproduction in Flatworms (Plathelminthes)


  • Fragmentation
  • Binary fission
  • Budding
  • Parthenogenesis
• Types of asexual reproduction in Blue-green algae (Cyanobacterium)


  • Fragmentation
  • Binary fission
  • Budding
  • Parthenogenesis
• Types of asexual reproduction in Honey bee (Apis mellifera)


  • Fragmentation
  • Binary fission
  • Budding
  • Parthenogenesis
• Types of asexual reproduction in Star fish (Asteroidea)


  • Fragmentation
  • Binary fission
  • Budding
  • Parthenogenesis
• Types of asexual reproduction in Warramaba Virgo grasshopper

  • Fragmentation
  • Binary fission
  • Budding
  • Parthenogenesis
• Sexual reproduction


  New organism from two organisms with the use of gametes. Sperm cell fuses with egg cell to form a diploid cell called zygote containing two sets of chromosomes. Genetic material contained in their chromosomes combine to produce genetically diverse offspring that are different from both parents.
• Stages of sexual reproduction


  • Gametogenesis
  • Fertilization
  • Implantation
  • Gastrulation
  • Embryonic stage
  • Fetal Stage
• Gametogenesis


  The production of gametes. Male: Spermatogenesis and produces spermatozoa. Female: Oogenesis and results in eggs or oocytes.
• Fertilization


  The process of a single sperm cell combining with single egg cell to form a zygote
• Implantation


  A process in which a embryo, moved in to the uterine wall and remains attached to it until birth.
• Gastrulation


  Stage which blastula is reorganized into a two-layered or three-layered embryo. Endoderm: Nervous system and epidermis. Mesoderm: Muscle cells and connective tissues. Endoderm: Columnar cells found in the digestive system and many internal organs
• Embryonic stage


  Formation of membranes, Development of placenta, Organ formations
• Fetal Stage


  This is when the embryo officially turns into a fetus, from ninth week until birth.
• Elephants have the longest pregnancy period of any living mammal. With nearly two years or 18 to 22 months.
• Octopuses are special creatures that reproduce only once during their lifetime.
• Male Seahorses Give Birth.
