classification of living things

• Kingdoms of life


  • Plantae
  • Animalia
  • Monera
  • Fungi
  • Protista
• Penguins can't fly in the air like most birds, instead they use their wings like flippers to move through the water
• Biological classification


  A system scientists use to sort all living things into groups based on their similarities
• Classifying organisms


  1. Describe what biological classification is

  2. Classify organisms based on their characteristics

  3. Explain the importance of classifying living things
• Biological classification helps us understand how living things are related to each other, makes studying and discussing the variety of life on Earth easier, and helps scientists quickly identify and categorise new species
• Binomial (two-part) naming system


  Each living thing has a name consisting of two Latin words: the genus and the species name
• Carl Linnaeus' system


  • Consists of a hierarchy of groups, from broad to more specific ones: Kingdom, Phylum, Class, Order, Family, Genus, Species
• Human classification


  • Animalia
  • Chordata
  • Mammalia
  • Primate
  • Hominidae
  • Homo
  • sapiens

  
• Plant kingdom


  • Most organisms can make their own food using sunlight, includes conifers, mosses, ferns and flowering plants
• Animal kingdom


  • Most organisms can move around and eat other organisms for energy, have specialised tissues and muscles used to perform complex functions
• Monera kingdom


  • Single-celled organisms with no defined nucleus, many found in extreme environments
• Fungi kingdom


  • Organisms get their food by breaking down matter around them, cell walls made of chitin
• Protista kingdom


  • Organisms that are neither plants, animals nor fungi, challenging to categorise since they have few things in common
• Vertebrate characteristics


  • Bones inside their bodies
  • Backbones or spine
  • Lungs or gills
• Invertebrate characteristics


  • Segmented bodies
  • Hard outer coverings
  • Jointed legs
