• Main groups of living things


  • Plants
  • Animals
  • Fungi
  • Protists
  • Bacteria
• Vertebrates


  Animals that have a backbone
• Invertebrates


  Animals that do not have a backbone
• Classifying


  1. Sorting living things into groups

  2. Based on similar characteristics
• specimen


  a dead and preserved one living thing
• Species


  a group of similar organisms that can breed with one another to produce fertile offspring
• biodiversity


  The number of different species that exists in habitat
• classification key


  A set of questions about the characteristics of living things
• DNA


  An uncoiled section of a gene that carry the code that controls what cells are made of and what they do
• variation


  The differences in members of the same species
• genetic variation


  Differences within a species inherited from the genes of both parents
• environmental variation


  Differences within a species affected by the surroundings of an organism. It affects how an organism looks and behaves
• dicontinuous variation


  Can only be one of a limited number of fixed options
• continuous variation


  Can take any numerical value in a large range of values
• fertilisation in animals


  When the egg fuses with the sperm to make a fertilized egg also known as a zygote
• pollination


  The transfer of pollen from the anther onto the stigma
• fertilisation


  When the nucleus from a male sex cell joins with a female sex cell to make a seed
• dispersal


  A mechanism which removes the seeds from the plant.So they can land in a suitable place to germinate into a new plant
• How can seeds travel


  • wind
  • bursting
  • animals
  • humans
  • water
• asexual reproduction


  When one parent produces new genetically identical offspring
• habitat


  A place where organisms live
• adaptations

  Special features that help an organism survive in habitat
• environment conditions

  • damp/ dry
  • windy/ humid
  • hot/ cold
  • bright/ dark
• categoric data


  When the thing we are changing is described by words or categories
