Sexual and Asexual 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 shown in the video?

  To illustrate human cell chromosomes
• 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 contribute to variation in offspring?

  It mixes genetic information from parents
• What is a key characteristic of asexual reproduction?

  Only one parent is involved
• What are the offspring of asexual reproduction called?

  Clones
• What type of cell division is involved in asexual reproduction?

  Mitosis
• How does the reproduction of the plant shown in the video occur?

  By forming tiny buds that grow into new plants
• What is the genetic relationship between offspring and parent in asexual reproduction?

  Offspring are genetically identical to the parent
• What are the main features of sexual reproduction?

  • Involves fusion of male and female gametes
  • Process called fertilization
  • Results in mixing of genetic information
  • Offspring show variation
• What are the main features of asexual reproduction?

  • Involves only one parent
  • No gametes involved
  • Offspring are genetically identical (clones)
  • Only involves mitosis
• What types of organisms perform sexual reproduction?

  • Animals
  • Flowering plants
• What types of organisms perform asexual reproduction?

  • Many plants
  • Some animals (e.g., aphids)
