  • Meiosis
    The process by which gametes (sperm and egg cells) are produced, with half the normal number of chromosomes
  • Normal human cells
    • Contain 23 pairs of chromosomes
  • Gametes (sperm and egg cells)
    • Contain 23 single chromosomes
  • Meiosis
    1. Chromosomes are copied
    2. Cell divides into two
    3. Both cells divide one more time forming gametes
  • Meiosis produces four gametes from one original cell, and each gamete is genetically different
  • Fertilization
    The joining of a male gamete (sperm) and a female gamete (egg) to form a new cell with the full number of chromosomes
  • Meiosis
    Halves the number of chromosomes
  • Fertilization
    Restores the full number of chromosomes
  • Embryo
    The clump of identical cells that forms after fertilization, which then differentiates into different cell types
  • Mitosis
    Cell division where one cell is copied into two identical cells
  • Gametes
    Cells where the chromosomes are not paired, e.g. sperm and egg cells
  • Meiosis
    Cell division that produces non-identical gametes
  • Meiosis takes place in flowering plants to produce pollen and egg cells
  • Sexual reproduction
    Involves the fusion of male and female gametes, mixing genetic information
  • Sexual reproduction results in variation in the offspring
  • Asexual reproduction
    Involves only one parent, no mixing of genetic information, produces genetically identical offspring (clones)
  • Asexual reproduction does not involve gametes or meiosis, only mitosis
  • Asexual reproduction in plants

    • Forming tiny buds that drop off and grow into new plants
