Sexual and Asexual Methods of Reproduction

• What is the definition of reproduction?

  Producing offspring.
• What are the two main types of reproduction?

  Sexual and asexual.
• How many parents are involved in asexual reproduction?

  1 parent.
• What is a key characteristic of offspring produced by asexual reproduction?

  Offspring is identical to parent organism.
• Why is asexual reproduction considered a faster way of reproduction?

  It involves only one parent and simpler processes.
• How many parents are involved in sexual reproduction?

  2 parents.
• What is a key characteristic of offspring produced by sexual reproduction?

  Offspring is different from each other (variety).
• What is the process that occurs during sexual reproduction involving sperm and egg cells?

  Union of sperm and egg cells.
• What are the methods of asexual reproduction in plants?

  1. Vegetative Propagation (roots, stems, or leaves)

  • Tuber (potato, sweet potato)
  • Runner (strawberry, kangkong)
  • Corn/Bulb (onion, garlic)
  • Rhizome (ginger)

  1. Spore Fermentation (mosses, ferns, mushrooms)
• What are the reproductive structures in a flower?

  • Male: Stamen (Anther, Filament)
  • Female: Pistil (Stigma, Style, Ovary)
• What are the steps in the sexual reproduction process in plants?

  1. Pollination
  2. Fertilization
  3. Seed formation
  4. Seed dispersal
  5. Germination
• What is binary fission?

  A method of asexual reproduction in bacteria.
• What is budding in the context of asexual reproduction?

  A method of asexual reproduction in yeast and hydra.
• What is regeneration/fragmentation?

  A method of asexual reproduction in starfish and lizards.
• What is internal fertilization?

  Egg is fertilized inside the female body.
• What is external fertilization?

  Egg is fertilized outside the female body.
• What are the advantages of asexual reproduction?

  • Produces more offspring
  • Only need one parent (easier)
  • Simpler process
  • Exact copy of parent
  • No variation
  • Preserves genetic continuity
• What are the characteristics of both sexual and asexual reproduction?

  • Types of reproduction in living organisms
  • Pass DNA from parent to offspring
• What are the characteristics of sexual reproduction?

  • Slower process
  • Need to find a mate
  • Mix of parents
  • Allows for high amounts of variations
  • Better at adapting to environment
  • Can involve mutations
• How does asexual reproduction differ from sexual reproduction in terms of offspring variation?

  Asexual reproduction produces identical offspring, while sexual reproduction produces varied offspring.
• What is the impact of mutations in sexual reproduction?

  Mutations can be harmful and affect offspring.
