Lesson Title: Today we are learning about
How does meiosis produce gametes?
Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding
Success Criteria: You will show your learning by...
  1. Students should be able to explain how meiosis halves the number of chromosomes in gametes and fertilisation restores the full number of chromosomes.
  2. Cells in reproductive organs divide by meiosis to form gametes.
  3. When a cell divides to form gametes: ? copies of the genetic information are made ? the cell divides twice to form four gametes, each with a single set of chromosomes ? all gametes are genetically different from each other.
  4. Gametes join at fertilisation to restore the normal number of chromosomes. The new cell divides by mitosis. The number of cells increases. As the embryo develops cells differentiate.
  5. Knowledge of the stages of meiosis is not required
Think about how you can match the needs of ALL students
Keywords:
  • Zygote: Cell produced from fertilisation. The first cell of a new organism. (1)
  • Fertilisation: Where gametes fuse and combine their chromosomes. (1)
  • Gamete: sex cells that fuse during sexual reproduction. (1)
  • Meiosis: cell division that forms unique haploid gametes. (1)

AFL/Key Questions:
  1. What happens to the number of chromosomes in gametes from meiosis? How is the full number of chromosomes restored?
    Meiosis halves the number of chromosomes. The full number is restored during fertilisation.
  2. How are gametes formed?
    Cells in reproductive organs divide by meiosis to form gametes.
  3. What happens when a cell divides to form gametes? Are the gametes genetically identical or different?
    First copies of the genetic information are made. Then the cell divides twice to form four gametes each with a single set of chromosomes. All gametes are genetically different from each other.
  4. What happens during fertilisation? What happens to the cells as the embryo grows?
    The gametes join and this restores the number of chromosomes. The new cell then divdes by mitosis and the number of cells increases. As the embryo develops cells differentiate.

Starter Activity Differentiation and Challenge question/task
  • Students to copy and complete the keywords.
  • Teacher reveals missing letters; Students correct mistakes;
  • Discuss the scientific meanings of the words.
  • Students to write down the definitions of the most important / new keywords.
  • Discuss the 'Memory Anchor'.
    • What does it show?
    • How does it relate to the what we are learning about today (title)?
