Sexual and Asexual Reproduction

Cards (21)

  • How many pairs of chromosomes do human cells contain?
    23
  • Why does the diagram show only four pairs of chromosomes?
    To make the diagram easier to see
  • In mitosis, how many identical cells are produced from one cell?
    Two
  • What are cells called where the chromosomes are not paired?
    Gametes
  • In humans, what are the two types of gametes?
    Sperm cells and egg cells
  • Are sperm cells larger or smaller than egg cells?
    Smaller
  • How many single chromosomes do human sperm and egg cells contain?
    23
  • What type of cell division makes gametes?
    Meiosis
  • How does meiosis differ from mitosis in terms of the cells produced?
    Meiosis produces non-identical cells
  • Besides animals, in what other organisms does meiosis take place?
    Flowering plants
  • In flowering plants, what are the gametes called?
    Pollen and egg cells
  • What type of reproduction do both animals and flowering plants carry out?
    Sexual reproduction
  • What is the fusion of male and female gametes called?
    Fertilization
  • What happens to genetic information during sexual reproduction?
    There is mixing of genetic information
  • Why does variation occur in offspring from sexual reproduction?
    Every gamete is different
  • In asexual reproduction, how many parents are there?
    One
  • Why does asexual reproduction not involve gametes?
    Because there's only one parent
  • What happens to genetic information during asexual reproduction?
    There is no mixing of genetic information
  • What are the offspring in asexual reproduction called?
    Clones
  • Which type of cell division does asexual reproduction involve?
    Mitosis
  • Are offspring plants genetically identical or different to the parent in asexual reproduction?
    Genetically identical
