  1. Types of Reproduction Asexual Sexual

  2. Heredity Table of Contents • 7.4.1 Notes • Asexual Reproduction Tree Map

  3. SPI 7.4.1—Classify methods of reproduction as sexual or asexual

  4. Purpose of Reproduction • To make sure a species can continue. • Definition: Reproduction is the process by which an organism produces others of its same kind.

  5. Asexual Reproduction • A new organism (sometimes more than one) is produced from one organism. • The offspring will have hereditary material uniform with the hereditary material of the parent organism. (The offspring will be genetically the same as the parent)

  6. Types of Asexual Reproduction • Budding • Regeneration or Fragmentation • Fission (Binary fission) • Spores • Vegetative Propagation

  7. Budding • Process by which a new, duplicate plant or animal begins to form at the side of the parent and enlarges until an individual is created.

  10. Regeneration or Fragmentation • The ability to restore lost or damaged tissues, organs or limbs. • It is a common feature in invertebrates, like worms and starfish.

  13. Fission • Also called binary fission. • Becoming two by division of the complete organism. • A type of cell division.

  16. Spores • A reproductive cell capable of developing into a new individual without fusion with another reproductive cell • Found in mold, fungi, and ferns

  19. Ferns

  20. Vegetative Propagation • A process which doesn’t involve a seed to produce new plants. • Examples: runners, bulbs, cuttings, grafting

  21. Bulbs

  22. Cuttings

  23. Grafting

  24. Runners

  25. Sexual Reproduction • Requires two sex cells – egg and sperm • The egg and sperm join to form an entirely new organism • Different from the parent organism

  26. Flowering plants

  27. Seeds

  28. Eggs

  29. Fish eggs

  30. Frog eggs

  31. Baby hedgehogs

  32. Baby animals

  33. Human babies

  34. IMPORTANT! • 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

  35. Sexual versus Asexual Reproduction

  36. Exit Slip • Describe the difference between asexual and sexual reproduction.
