Asexual and sexual reproduction

• What are the two types of reproduction discussed?

  Sexual and asexual reproduction
• How many pairs of chromosomes do human cells contain?

  23 pairs of chromosomes
• What is the purpose of the diagram showing human cells?

  To illustrate chromosome pairs
• What process do cells undergo to divide into two identical cells?

  Mitosis
• What are gametes in humans?

  Sperm cells and egg cells
• How many chromosomes do human gametes contain?

  23 single chromosomes
• What type of cell division produces gametes?

  Meiosis
• How do gametes differ from somatic cells?

  Gametes have single chromosomes
• What is a key difference between meiosis and mitosis?

  Meiosis produces non-identical cells
• What are the gametes in flowering plants?

  Pollen and egg cells
• What is the process called when male and female gametes fuse?

  Fertilization
• What does sexual reproduction result in regarding genetic information?

  Mixing of genetic information
• How does sexual reproduction lead to variation in offspring?

  Due to genetic mixing from parents
• How many parents are involved in asexual reproduction?

  One parent
• What are the offspring of asexual reproduction called?

  Clones
• Why does asexual reproduction not involve gametes?

  There is only one parent
• What type of cell division occurs in asexual reproduction?

  Mitosis
• How do offspring plants produced by asexual reproduction compare to their parent?

  They are genetically identical
• What are the key features of sexual reproduction?

  • Involves fusion of male and female gametes
  • Results in mixing of genetic information
  • Produces variation in offspring
• What are the key features of asexual reproduction?

  • Involves only one parent
  • Does not involve gametes
  • Produces genetically identical offspring (clones)
  • Only involves mitosis
• What are examples of organisms that reproduce sexually and asexually?

  • Sexual: Humans, flowering plants
  • Asexual: Aphids, certain plants
