B1.1 Classification

  • Aristotle was the first to sort organisms into groups based on their characteristics ( Classification
  • Phylum, Class, Order, Family, Genus, Species
  • Multicellular ~ made of many cells
  • Unicellular ~ single cell tha contains a nucleus, But bacteria are simple with no nucleus
  • Plants get their food autotrophically by using photosynthesis.
  • Animals feed heterotrophically by eating and digesting other organisms.
  • Saprophytically feeding is done outside the body
  • There is no place for viruses inside the kingdom because a virus changes the way a cell works and causes it to make copies of the virus. however it doesn't show other life processes.

B1.2 Vertebrates and Invertebrates

  • Vertebrates are animals that have a backbone. These are a series of small bones called vertebrae.
  • All vertebrates belong to the Phylum Chordata because they have a supporting rod that runs the length of their body.
  • Invertebrates are animals that don't have a backbone.
  • 5 animal kingdoms; Fish,Mammals,Reptiles,Amphibians and birds.
  • Some vertebrates reproduce using external fertilisation.
  • Other vertebrates reproduce internally.
  • Vertebrates who lay eggs are oviparous.
  • Vertebrates who give birth to live young are vivparous.
  • Homeotherm ~ this means they keep their body temperature is more constant.
  • Poiilotherms ~ this means their body temperature varies. 
  • Verterbrates are placed into groups on; Respiration methods; lungs, gills and skin. Reproduction; oviparous, viviparous. Thermoregualtion; homeotherms, poikelotherms. 
  • There is a problem when assigning vertebrates to a specific group because some animals may have more than one characterisitc.
