Classification Notes

The document outlines the five kingdoms of living things - animals, plants, fungi, protoctists, and prokaryotes. It describes the main features of animals as multicellular, containing a nucleus but no cell walls or chloroplasts, and feeding on organic substances made by other organisms. The main features of plants are described as multicellular, containing a nucleus, chloroplasts and cellulose cell walls, and feeding through photosynthesis. The animal kingdom is further divided into vertebrates, which have backbones, and invertebrates, which do not have backbones.

 The first division of living things in the classification system is to put them into

one of five kingdoms. They are:


o Animals
o Plants
o Fungi
o Protoctists
o Prokaryotes

 Main features of all animals:


o they are multicellular
o their cells contain a nucleus but no cell walls or chloroplasts
o they feed on organic substances made by other living things

 Main features of all plants:


o they are multicellular
o their cells contain a nucleus, chloroplasts and cellulose cell walls
o they all feed by photosynthesis
The Animal Kingdom

 Several main features are used to place organisms into groups within the
animal kingdom

Vertebrates

 All vertebrates have a backbone


o There are 5 classes of vertebrates


Invertebrates

 Invertebrates do not possess a backbone


 One of the morphological characteristics used to classify invertebrates
is whether they have legs or not
 All invertebrates with jointed legs are part of the phylum Arthropods
 They are classified further into the following classes:
