Definition: Asexual Reproduction

Asexual reproduction involves a single parent passing genetic information to create exact copies of offspring. Learn examples like binary fission in bacteria and budding in hydra. In contrast, sexual reproduction involves two parents combining genetic characteristics through fertilization to create diverse offspring types. Discover the fascinating world of spore production in fungi and fragmentation in segmented worms. Explore different types of fertilization like external and internal, seen in organisms from fish to mammals.

Presentation Transcript

  1. Definition: Asexual Reproduction A single parent passes genetic information to the offspring which will produce an exact genetic copy.

  2. Asexual strategy example 1 • Example: Binary fission • Description: The parent organism divides into two separate organisms called daughters. • Type of organism: Bacteria (Kingdom Monera)

  3. Asexual strategy example 2 • Example: Budding • Description: A cell “bud” grows on the parent organisms. It develops on the parent then breaks off. • Type of organism: Hydra (Kingdom: Animal) Lives in the ocean

  4. Asexual strategy example 3 • Example: Spore production (Sporogenesis) • Description: Spores are formed through mitosis and dispersed like seeds. (NOTE: There are other ways spores are formed.) • Type of organism: mushrooms (Kingdom: Fungi)

  5. Asexual strategy example 4 • Example: Fragmentation • Description: A new organism grows and fully develops from a piece or fragment of the parent. • Type of organism: Segmented worms (Kingdom: Animal)

  6. Sexual Reproduction • Definition- Two parents produce offspring that have genetic characteristics from both parents. • By means of Fertilization: • Definition: Fertilization- The combining of male (sperm) and female (egg) to produce a zygote that has half the DNA of each parent.

  7. Two Types of Fertilization • 1. External Fertilization “Spawning” • Eggs are layed in water and male releases sperm near them. • Type of organism: Salamanders and Newts • Type: Fish • Type: Frogs and Toads

  8. 2. Internal FertilizationDescription: Eggs are fertilized inside of the female’s reproductive tract. • Type of organism: Snakes • Type of organism: Mammals (Whales, kangaroos, humans) Birth live young • Type of organism: Birds lay eggs after fertilization
