1. Sexual and Asexual Reproduction.

2. Asexual Reproduction:
One parent producing an offspring identical to itself (parent)
Offspring can live independently

3. Cell Division in Unicellular Organisms
Binary Fission:
form of asexual reproduction in prokaryotic (lacks nucleus) organisms
Parent organism splits in half
(Eukaryotic – reproduce by mitosis ex: algae, some yeast, protozoans like paramecium)

5. Budding Organism develops tiny buds on its body Asexual reproduction
Buds form from the parent cell so the bud is identical to the parent.
Both unicellular and multicellular
Examples: hydra, plants, some yeast

8. Regeneration:
Specialized cells grow new tissue when a wound or lost limb occurs
Examples: Starfish, lizard tails, planarian, cuttings from plants….

10. Asexual Reproduction & Health
Bacteria reproduces at very rapid rates
Reason you get sick within a day..

14. Spore Formation – spores = small specialized cells that contain a nucleus and cytoplasm surrounded by a thick outside wall which protects the spore. Under the right conditions the spore can rise to a new organism. Found in bacteria, molds, yeast, mushrooms, mosses, ferns and some protozoans.

16. Sexual Reproduction Two parents egg (female) and sperm (male)
Fertilization – when egg and sperm unite
Plants growing from seeds and animals growing from eggs
Creates the diversity of life on earth
Offspring is unique

18. Asexual Reproduction One parent Identical to parent
More likely to get disease
Binary Fission, budding, regeneration, spore formation

19. Sexual Reproduction Two parents – male and female
Unique offspring ( not identical to parents)
Egg, sperm
Fertilization ( egg and sperm unite)
More resistant to disease
