B6- Reproduction

• What are the two main ways organisms can reproduce?

  Sexual reproduction and asexual reproduction
• Which organisms can reproduce through both sexual and asexual reproduction?

  Some plants
• What type of reproduction do most animals rely on?

  Sexual reproduction
• How do bacteria reproduce?

  Asexually
• What is the key point of sexual reproduction?

  It involves the fusion of male and female gametes
• What is fertilization in sexual reproduction?

  The fusion of male and female gametes
• Why are offspring from sexual reproduction genetically different?

  They contain a mixture of their parents' genes
• How many chromosomes does a normal human cell have?

  46 chromosomes
• How many chromosomes do human gametes have?

  23 chromosomes
• What happens when two gametes fuse together?

  The resulting cell has 46 chromosomes
• What process produces gametes?

  Meiosis
• Does sexual reproduction require sexual intercourse?

  No, it refers to gamete fusion
• How do plants reproduce sexually?

  Through the combination of pollen and egg cells
• What is a key characteristic of asexual reproduction?

  It involves only one parent
• What is the result of asexual reproduction?

  Identical clones of the parent
• How do eukaryotic organisms reproduce asexually?

  Through mitosis
• How do bacteria reproduce asexually?

  By binary fission
• What are the differences between sexual and asexual reproduction?

  • Sexual reproduction:
  • Involves two parents
  • Fusion of gametes
  • Genetic variation
  • Asexual reproduction:
  • Involves one parent
  • No gamete fusion
  • Identical offspring
• What are the processes involved in sexual and asexual reproduction?

  • Sexual reproduction:
  • Meiosis produces gametes
  • Fertilization occurs
  • Asexual reproduction:
  • Mitosis for eukaryotes
  • Binary fission for bacteria
