CLASSIFICATION OF LIVING THINGS

We are studying the classification of all living things in ESO 1. In this post I have summarised the groups we have seen so far.  At the moment, I only intend to mention the groups, without going into detail. Make sure you know these groups well!
 Living things are classified into  5 kingdoms:
ALL LIVING THINGS:
  • Monera Kingdom               bacteria and cyanbacteria
  • Protoctist Kingdom               protozoa and algae
  • Fungi Kingdom                     yeast, mould, mushrooms
  • Plant Kingdom                      mosses, ferns, flowering plants
  • Animal Kingdom                        invertebrates, vertebrates

ANIMAL KINGDOM - INVERTEBRATES:
  • Porifera                                     sponges
  • Cnidaria                jellyfish,polyps,sea anemones
  • Worms           nematodes,platyhelminthes,annelids
  • Molluscs           gastropods,bivalves,cephalopods
  • Echinoderms           echinodea,stelleroidea,crinoidea,holothuroidea,ophiuroidea
  • Arthropods        insects,arachnids,myriapods,crustacean
Look at these posters of invertebrates, these are last years. We will do something similar soon.







Now check out this really interesting link! It's an extremely exhaustive web page about insects. It has photographs and commentaries of a great number of insect species. Remember, insects are athropods, so they have a segmented body, an exoskeleton and jointed appendages. Insects have 3 body parts (head, thorax and abdomen), 6  legs, 2 antennae and 2,4 or no wings.
